I think our culture is a man's home is his castle and his car is an extension of that. Most of us travel into work and back by car and have not been tempted by car sharing schemes because we value our freedom too much and want to keep the flexability having a car brings. Our weather is not conducive to cycling for much of the year and most city roads and car drivers are not cyclist friendly.
However car drivers are being hit hard in the pocket, and it will get worse. I can see a time in the not so distant future where we will look back and tell our grandchildren that each person owned a car. Then, when the choice is public transport, a motorbike or scooter, or a pushbike, we might see the electric bike as a popular choice of transport.
