I think Tesla does have options for strength of regen, correct? Although none of them are true one pedal driving options like on the Leaf or Bolt.
It is not at all necessary to feather the "go pedal"! Unless I'm in bumper to bumper traffic, I use cruise control on my Bolt once I get to speed. Then I just sit back relax my foot next to the brake in case I need to make an emergency stop.
If I need to increase or decrease speed with cruise control on, I do so with the + and - controls on the steering wheel. If I need to slow for a stop sign or traffic light, I pull the trigger/paddle on the back of the steering wheel to engage max regen and disengage cruse control. If I need to stop suddenly, I pull the regen trigger/paddle and hit the brakes.
Once you're used to it, it's hard to go back to the fake "creep" mode.
If you follow Tesla owners on forums and such, they do exactly what you are talking about. Tesla Motors Club is filled with discussions about issues, poor service center visits and what have you.
Tesla owners are about the same as any other car owner - they love their car and it is very personal purchase for them... but they absolutely whine and complain when things go wrong!
