The idea is simple. For those long trips. Why can’t we adapt our transportation system to bring our cars with us on the train. This would increase the range for electric cars and reduce car emissions for those gasoline wasting combustion engines. Not only that but not everyone likes to drive 300 miles in one day. Thus increasing safety for all on board. So the idea is that you still want to have your car at the destination your going to even though you don’t want to drive all the way to it. You just bring it with you on a train transport.
