I personally think there are very few things we need today more than self driving cars. Driving is one of the most dangerous things we willingly do in our daily lives. There is an insane amount of valuable space in cities devoted to roads and parking, which is all used inefficiently. Valuable time is wasted in commutes and traffic.

Now imagine if every driver on the road followed all rules. Traffic flowed smoothly and there were fewer accidents. Your car dropped you in the middle of the city and drove out of sight till it was needed again. No one ever drove drunk or impaired. You could catch up on work or just watch something during your daily commute.

Now imagine strong wind brought down a tree branch on the road. A strong rain crated a big puddle. Etc. There is a lot more to driving than just following the rules. And I do no see how self driving car reduce the need for roads. Or parking. And the time spend waiting for them to arrive can be significant.
