I was all excited about Cybertruck when they were first announced so I went in on two reservations. Did it through someone affiliated with Tesla so not in my name but the trucks would come to me.
I changed my mind and decided I didn't want a Cybertruck. Maybe I'll change again when I actually see the thing and get to drive it and get familiar with it. But I don't want one right now.
It was no problem cancelling for me. There are plenty of buyers who do want them.
