One concern I'd have is if you wished to revert to car ownership, you would be heavily penalised with insurance costs as you would no longer have a no-claims history.
Yes, it's a valid concern alright Leo.
Personally, I have a full no claims bonus for example, so I would not like to lose it and yet, I feel the insurance companies are taking advantage of us all regardless of what our history is, so I'm not sure it's really that great a benefit.
I guess it's a case of trying to figure out how many years paying no private car insurance would you need to "breakeven", in terms of the likely cost of having to pay a premium with no discount for no claims, if you ever went back to private car ownership again in the future ?
Obviously, the above is only one part of the overall calculation though, when you also then consider the cost of tax, car servicing, possible car finance and then also make allowance for the costs associated with using GoCar.
In the case of the two lads that I was referring to, both live and work in Dublin and while both travel a bit for work, I don't think either actually see themselves ever becoming car owners again (which in itself is an interesting point, given both are only mid 40s, have active social and family lives etc.).
