Sharing Your Car on odo.ie: Co-drivers vs. Households

What’s the difference

Both features let other people see your cars in odo.ie, log fuel and services, and keep the records rolling. They just work at different scales and with different ergonomics.

Co-drivers (1:1 sharing)

You pick a specific car, type a specific email address, send an invite. Once accepted, that person can log activity on that one car. Nothing else of yours. They don’t see your other cars, you don’t see any of theirs. It’s a one-way grant from owner to co-driver. Think of it like letting a second key exist — they can drive and log, but the car remains yours.

Co-drivers is a Family/Pro-only feature to send or accept. Practically: two paying Irish users who each have their own account, granting each other access to specific cars.

Household (group sharing)

You create a household (say "The Murphys"), give it a name, invite up to 5 other people. Once they accept, everyone in the household sees everyone’s active cars — owned by any member — in one combined dashboard. Combined fuel spend this month, total family km, all service records, the lot. Every member can log activity on any household car.

Creating a household is Family/Pro. But joining is open to any tier including Solo, because that’s how family plans work in the rest of the industry (Spotify Family, Apple Family, Netflix Household). The subscriber hosts, members ride along free.

Side-by-side comparison

When Co-drivers fits — scenarios

Co-drivers is best when the sharing is specific and bounded. You know exactly which car, exactly which person, and the relationship isn’t "we all live here and share everything".

1. The occasional partner. Your boyfriend / girlfriend drives your 2016 Focus once a week when yours is in the garage. You want him or her to be able to log fuel when they fill up, but the car is yours and stays yours. Co-drivers on that one car.
2. The adult child learning to drive. Your 19-year-old is on an L-permit using your Polo for practice. You want them logging the km they put on, without giving them access to your other cars or any editing rights. Co-driver on the Polo; they can see the odometer climbing and you get the trip history.
3. The mechanic during a service. You’re dropping the car at a trusted independent for a full service. You want them to be able to see the full service history as they work and optionally add a service entry afterwards. Co-driver access, time-limited — revoke once the invoice lands.
4. Self-employed accountant access. Revenue civil-service-rate logbook for a work-used car. Your accountant needs to see the mileage and fuel data at year-end but shouldn’t be messing with your personal car records. Co-driver on the work car only, read-only behaviour in practice (no destructive actions).
5. The long-term loan car. Your brother is home from abroad for the year and using your old Megane. You want him to log fuel and services as he goes; when he leaves the country you’ll revoke. Co-driver on the Megane for the year he’s here.
6. The carer or helper. Someone who runs errands in your car a couple of times a week — a carer, a family friend taking Mam to appointments, a cleaner who does the Tesco run. They put fuel in. Co-driver access lets them log those fills without bothering you.
7. Neighbour car-share arrangement. You share one second car with your neighbour (uncommon but it happens around Dublin 2–7). Co-driver on that car — they log their trips, you log yours, €/km tracked fairly.
8. Temporary "prospective buyer" access. Before selling, you’re showing a serious buyer the car. You want them to be able to browse the full service history for due diligence. Co-driver access they can read, revoke after the sale.

When Household fits — scenarios

Household is best when there are multiple cars, multiple people, and the relationship is "we’re all in this together". You want a combined view, not a set of individual shares.

1. Classic couple with two cars. You on a 2021 Golf, partner on a 2019 Fiesta. You both want to see this month’s combined fuel spend across both cars — because the bank account is the same account. Household rolls both into one dashboard.
2. Family with adult kids driving the family car. Two parents on a Tiguan and a Yaris, one adult child home from college also driving the Yaris on weekends. Everyone logs their fills. Service history captures who did what. Household with 3 members; both cars visible to all.
3. The classic "his / hers / shared" setup. Three cars — his daily, her daily, the shared weekend car. Both of you want to see the two dailies in a combined view for budgeting, plus the weekend car for everyone. Household of 2, three cars flagged in.
4. Multi-generational household. Parents, an adult son, his partner all living together, four cars in the driveway. The mother-in-law does the big-family-Tesco run in her Zafira, the son and his partner share the new EV. Everyone in one view for household-level €/km. Household of 4, all cars rolled up.
5. Small family business with a few vans. You run a small landscaping / plumbing / delivery business out of the home. The van is technically a business vehicle but it’s serviced alongside the family cars. Two or three family members drive it. Household (up to 6) with the van plus everyone’s personal cars — one fuel spend total for the household+business.
6. Flatmates sharing a car. Three housemates chipped in on a 2014 Civic for getting to work. Any of them logs the fuel when they fill up; expenses split fairly at the end of the month. Each of them also has their own runabout they want visible to the group. Household of 3, four cars between them.
7. Co-parenting across two homes. Separated parents with a shared child; each has a car; they want to coordinate who is picking up from school this week and track the mileage attributed to pickups / drop-offs. Household of 2 where both cars are visible but specific trips can be logged-by whichever parent drove.
8. The "caravan / bike / car" combo household. A car, a caravan (classed as a vehicle in odo.ie), a 125cc motorbike for weekend runs. Two adults using different combinations of these. Everyone needs to see combined ownership costs. Household of 2, all three vehicles flagged in.
9. Supporting ageing parents. Your parents are in their 70s, still driving an Aygo. You manage their NCT / motor tax / insurance renewals for them — and want to log their fuel for them when you see them at the weekend. Household of 3: you, one parent, their car; you do the admin work for them.
10. Expat family running a car for a relative. You live abroad but pay the upkeep on a car back home that your sister uses. You want oversight on fuel and service costs without bothering her with admin. Household of 2 with the one car — she drives and logs, you review.

Using both together

They’re designed to coexist. A realistic Irish example:

• You and your partner are in a household of 2; both of your cars are visible to each other.
• You also have a 1:1 co-driver share with your long-time mechanic on your Focus, so he can browse the service history when the car comes in for a service.
• Your partner has a 1:1 co-driver share with her accountant on her self-employed car so the mileage and fuel data is visible at year-end.

The household sharing and the 1:1 co-driver shares are completely independent. Leaving the household doesn’t revoke your mechanic’s access; revoking your mechanic’s access doesn’t affect the household. Archiving a car removes it from household visibility but your mechanic keeps his read-only history.

How it works step-by-step

Starting a household

1. Open the avatar menu in the top-right and click Sharing & Household.
2. Click Household, give it a name (e.g. "The Murphys").
3. All of your active cars are flagged into the household by default — you can toggle any specific one back to private later.
4. Click Send invite and enter the email of the person you want to add. They’ll get an email with a 7-day link.
5. When they accept, their cars appear in everyone’s combined dashboard and your cars appear in theirs.

Inviting a 1:1 co-driver

1. Open the avatar menu and click Sharing & Household.
2. Click Co-drivers.
3. Click the plus icon next to the car you want to share, enter the person’s email.
4. They get a 7-day invite link. Once accepted, they see that one car only.
5. Revoke any time from the same Co-drivers page.

Switching a car in or out of your household

1. On the Household page, scroll to "Your cars in this household".
2. Flip the toggle off to keep a specific car private; flip it on to share.
3. You can also toggle this from each car’s Edit vehicle form.
