I don't think we'll see "long distance ubers" as a separate service - you'll just get into one and have it take you an hour away. Which, with proper road infrastructure, will naturally get to be about 100-200 km in less then 10 years or 200-300 later. You don't really need a toilet for that - or if you do, you just make a stop at a gas station, and have it wait or get another. Remember that Europe is not US - it's pretty much urban space next to urban space, not hundreds of miles of nothing. And for longer distances you fly (or yes, you get a high speed train)
