It depends on the car. Mine is resistive (like yours I think) and I can just press harder, I also don't have to use my fingers, something like a capped pen works perfectly. Though these kinds of screens are considered low-end compared to capacitive touchscreens because they require a heavy touch and usually don't support multitouch, I think these are the best for cars (if you don't have physical controls).

But many modern cars (ex: Teslas) use capacitive screens like on smartphones.
