We also used the bikeshare system - complete with goofy helmets:
Most of the time it was necessary for at least a couple of us to ride like criminals without the plastic hat. They were so often not available. Quite often the reason for their lack of availability would ride past you:
(To be fair, I am sure that young lady bought her bikeshare helmet for $5 from a 7-Eleven and quite rightly kept it given that she had paid for it).
While there, we caught up with friends; two families who have moved from Adelaide to Melbourne in the last year. Both families are very similar - two children; both at school and similar ages; one boy and one girl; do different activities at different times.
As you would expect, both were two-car families when they lived in Adelaide. Unless you make a really concerted effort, it is quite difficult for a family like that to function normally in Adelaide without two cars. It can be done but as I say, it requires real effort.
In the short time they have been living in Melbourne (less than twelve months), both have got rid of one car.
Getting into the city is much cheaper, quicker and easier by tram. That means some children's activities can be reached that way. It also means the children (some of the time) can get there by themselves. Once of the dads has even got himself a year's subscription to bikeshare.
Melbourne is far from a world leader in public transport and biking infrastructure. Public transport is excellent by Australian standards but could still improve and biking as transport has massive scope for improvement. Despite that, Melbourne still offers sufficient transport choice for families like that not to have to fund two cars. Add up all of the families in that position and then work out the money they are saving and what it can be spent on. Then the wider benefits start to materialise.
Further improvements would merely improve mobility and independence, particularly for the children in each family.
I think once a city can boast that sort of choice, you know it is getting somewhere. And once we get to the point where people genuinely have the choice not to own a car, only then will be able to rest on our laurels - and then only for a short time.
