Hopefully you have a 14-30 outlet if you have a 30 amp breaker.
For EVs (continuous load), you can only use 80%, so it would be 24 amps usable, not 30 amps.
A 2021 Model Y LR is rated at 270 Wh/mile: 24 amps * 240 volts / 270 Wh/mile = 21.3 mph.
A 2021 Model Y Performance is rated at 300 Wh/mile: 24 amps * 240 volts / 300 Wh/mile = 19.2 mph.
