I will go against the grain and say that test driving an EV won't help. Here's why:
My first post on these forums (almost 8 years ago) included some of the same thoughts on possibly missing shifting and ICE sounds. I always bought manual-transmission cars, and my motorcycle engines spent most of their lives near the rev limit.
The first time I drove an EV, of course I noticed it was quiet and I didn't have to shift. But I didn't appreciate them yet.
As RangerRick noted, we like shifting and feel "in the flow" when we do it because it gives us precise control over the car's powerband. But an electric motor is already there. You have the same control over the power; you just don't have to move a stick to get it. It took a few weeks of driving electric to get used to the new method, but now I don't miss shifting at all.
Sound is similar. Loud sounds aren't awesome on their own. We like them because we associate them with power - the sensation of being accelerated quickly. But if you drive electric for a few weeks, your brain will learn a new association. My Roadster always sounded like a remote pod-racer, and I freaking loved that sound. (Note that if you don't exclusively drive electric, but switch back and forth with a gas car, your brain's associations will not change in the same time frame).
In short: concern about performance cues (i.e. shifting and noise) is very common. I had the same concerns. But after a few weeks of driving an EV, I don't think you will miss them at all. Plus, as others pointed out, even if you were to miss them, there are plenty of other EV advantages you will have gotten used to that you won't want to give up.
Whatever you do, good luck and enjoy!
