We have Uber Volvo's self driving here in Pittsburgh area god help you if you get stuck behind one. It will make following a city bus or garbage truck seem pleasurable.
I 100% agree with the previous statement about self driving semi trucks, not only because my livelihood depends on one, having a 40+ ton truck making a non emotional decision between you and that bright yellow school bus that may not even have a single child on it. If one does hit you who are you suing, a giant corporation, good luck with that, they will outlived you and your heirs, or they will fold up, and grow anew someplace else.
Intermodal transportation make 100 times more sense than trying to get a truck to drive across the country by itself on the roads and all the variables. Who is checking the load enroute, is it going to fall off and squish you like a grape, is it going to leak out and contaminate the road, water, you. Who is pre-tripping the truck and trailer spotting cracked wheels or separating tires before they come apart in the lane next to you. Are they just going to stop on the shoulder of a crowded road and send a email for road service because the turnsignal is out (it is a red tag offense with mandatory out of service), or does it make a decision to break federal law and continue without it or at a minimum, make a desicion that a large vehicle on the side of the road in that spot is dangerous to others. If it does stop, who puts out the safety triangles or flares at night. With one hundred containers on a train not on the road it is solving a congestion problem also. Talk about getting so caught up in a idea that you can't see the absurdity of the end result.
Self driving cars will happen. Most people can't stand driving now but don't want to take public transportation because the schedule or crowd.
