Ask for an extended test drive, and take it home and try it out, see how easy or hard it is to reverse. Tesla has mastered low speed accelerator modulation and gentle power delivery. It’s really good. Combined with auto hold that smoothly blends in brakes, reversing uphill is a piece of cake.
What do you currently drive? An automatic combustion car is harder due to fluctuating power levels as engine revs. A manual would be even harder when adding in the clutch - that takes full concentration. If you currently drive a hybrid, it’d probably feel about the same.
