When I test drove a Model 3, it really was weird getting back into my STI. You become accustomed to the NVH of an ICE to the point that it is jarring when it is taken away, then put back.The real review is when you actually climb back into your old car and say to yourself "WHAT?? no regen? Why is it so loud? Why do I need a transmission? Brake pedal is stupid!!"
But for real, I'm looking forward to hearing what you think after you get your old car back.
