Cars of any sort, self-driving or otherwise, do not solve traffic any more than Uber does because you need to have enough of them to get everyone to and from work at basically the same time. Trains are the only way to address traffic. Trains are self-driving. Europe already has the better self-driving system. It's just boring because self-driving is much easier when you build the road to support it instead of removing all constraints and adding GPUs, lidar sensors, cameras and an army of fall-back operators in overseas call centers.
