Judging by how frequently I occasionally lose internet connection for a mile or two in my major metro area for even basic tasks, like Siri dictation or streaming audio, I can't imagine how remote takeover could possibly be the answer to the "10%" situation unless we're prepared for some percentage of the time we are faced with a truck that simply gives up, puts on four-way flashers and comes to a stop wherever it may be (which could include network dead zones)... and then it's a matter for the police and/or recovery workers to either get the AI back in the saddle or move the truck.
