Almost all cars can be set to respect a speed limit already; I do that when I drive on highways to make sure I don’t accidentally go over (which is easy to do especially when others around me do it). Outside of the US (and perhaps a few other places, but not many), speeding tickets are not designed to be a revenue source. (They do produce revenue, of course - but are not optimized or planned for that purpose)
