Yes, but the thing with electric cars is that so long as the recharge rate is faster than the depletion rate the shorter your overall time. For example:
I drive the 150 miles between my house and Harris Ranch in my Model S at 62.5 mph and achieve the rated range of 3.3 miles/kwh.
- time used 144 minutes
- kWh used 45
- supercharge time 30 minutes (@90kW)
- total time 174 minutes
I drive the same 150 miles at 75 mph and only get 2.5 miles/kwh
- time used 120 minutes
- kWh used 60
- supercharge time 40 minutes (@90kW)
- total time 160 minutes
I'd rather go faster. It saves on overall time. At least it does when you can utilize a supercharger network.
