The problem isn’t that no one’s thought of those things. The problem is that in Countries like the US and UK (and I’m assuming everywhere else, but maybe not) you can tow up to 7500lbs with a standard license. Last time I took my test I don’t recall them asking about towing or making me do it with a trailer. We build systems for the lowest common denominator but honestly vehicle towing is kind of a cluster fuck of “well they can drive a car, how much worse could they be with an extra 15ft and thousands of pounds behind them.” ¯_(ツ)_/¯
