This is not the best plan as your car will probably smell. But sometimes you have to dry your wetsuit in the car when you are going somewhere and you cant leave your wetsuit hanged outside over the fence or something. So you’ll lock it in your car. The problem here is ventilation, without wind and fresh air air in the car will soon become saturated with moisture and the wetsuit will stop drying. So you should leave your car windows opened at least a little bit. Next thing is where to put it? If you have a car that is high enough to hand your wetsuit in it then this is the best way. Put the bottom of your wetsuit in a plastic box and hang the top somewhere in your car. And let the gravity do its work and drain some water from the wetsuit. Actually this is a smart thing to do even if you have a small car. If you can not hang it then there is not much you can do. Just don’t leave it in a plastic bag :). Cover your sit ith some plastic bags and throw the wetsuit over it or something… Or you can also get a hangair wetsuit drier that can be pluged in your car and your wetsuit will be dry in a couple of hours.
