Re: Hailing a self driving car?
'Newflash - there are already these things called "taxis" (maybe you've heard of them?) that you can hail that have been around since before the internal combustion engine was invented.'
Actually they existed before the internal combustion engine was invented.
But one of the problems is that most people want to travel at fairly restricted times of the morning and evening. If you provided enough taxis to meet these peak demands you'd find them underused for the rest of the day and, given the need for them to make a profit, most of their operators would go out of business over time. The number of taxis reduced to something like present day levels, namely, unable to provide an adequate service to most people at the times they want to travel.
The consequence is that most people who need to commute, at normal commuting times, between endpoints where public transport doesn't make much sense, find they need to make their own provision. They buy a car.
