Just to put some numbers on it. A standard outlet is rated for 1440 watts under continuous load (1800 * 80% per NEC) or 1.44 kWh. A Tesla Model 3 travels around 4 miles per kWh. So each hour of charging provides between 5-6 miles of range. Installing a 240V/30A "dryer" outlet would allow charging about 4X faster.
Personally, we own a Chevy Volt and get about 3.5 miles per kWh out of it. I installed a 240V/30A outlet in our garage, but the Volt's max recharging rate is 4 kWh. Still that gives us 14 miles/hour.
