Re: Asking people if they're willing to share
"There are several reason I won't share a car but with relatives. Hygiene is one reason, probably the main one, but not the only one
waiting ten minutes for one to arrive would be too much - especially if there's an emergency."
Wow to the first point. Looking at cars parked in streets around here - you are in a special class, a small class.
Second point. Waiting 10 mins for car - you mean not walking 10 minutes to the spot you took another 10 minutes to find? The success of Uber despite all its downsides is sharing is attractive to a large proportion of the population of a large city. Uber just found a new and more efficient mechanism for enabling that rather than the minicab market before.
Being able to call up a minicab without an undesirable driver looks to be an even more attractive and more efficient (ie cheaper) option.
Will that expand the market? Moot point. Paying the real cost of every journey as opposed to just jumping in the car without thinking about it might make the choice of other methods (walk/bike/bus/train) more realistic.
Plus congestion around here is caused more by parked cars than moving traffic. The easiest/cheapest way of increasing traffic flow is to not having parked vehicles obstructing it for 23 hours a day.
Plus flexibility. A autonomous car for two for a nice night out, a Winnebago for a nice week out. You don't have to buy both. You can do other things than stare at the road ;-)
