I wish. Public transit exists here (our system even wins national awards), but it's terrible. To commute to work, for instance, would take over an hour, but I can bike the distance in under 20 minutes.
So, bike for the win!
Which, to be honest, isn't a huge lifestyle change for me anyway. I own and use a car when needed, but the bike is my primary transportation. It's faster, more convenient, and more pleasant under most circumstances.
public transit already is subscription model: you buy a ticket for a ride, or the monthly pass. It is even easier to deny you access to some form of public transport already (think subway entry gates, or long distance trains where you cannot really avoid ticket check). All this follows Klaus Schwab vision for the mankind "you'll own nothing and you'll be happy".
