Is that not the point of a 14-50 socket? To say that you can draw 50 amps? If you can't supply 50 amps without tripping a breaker, don't install a 50 amp socket.
Also, a bog standard 14-50 is likely not suited for 80% steady EV usage anyway. They make EV-rated 14-50s now because people keep melting the older ones. And that happens even though the vast majority of chargers won't draw more than 32A on a 14-50 due to the historical popularity of using 40A breakers for a 14-50 receptacle.
