Streetcar is a car-pooling business which allows people to hire car on a time-share basis with other people in the area.
They now have a car parked on Foxberry Road for members to use.
This is probably an offer that will appeal to a limited range of people - for short journeys it's often easier and cheaper to get a mincab and for longer periods, how far you plan to drive will determine whether its cheaper to hire a car in traditional fashion. For regular drivers, it's cheaper to buy a car.
Still, some people obviously find that it works for them and Streetcar claim that the kind of car-sharing they offer reduces the number of cars on the road (or more accurately, pavement), so it's a very welcome addition to the area.
