| For me, it doesn't matter what car, what time of the year, I always get zapped. I also get zapped on things like freezer doors at the supermarket (really embarrassing when you let out a yelp!!)
As others have mentioned, the best way to deal with this is to 'earth' yourself as you get out of the car, by making sure you are holding on to the metal part of the car. This has become habit for me - and I don't really even need to think about it now. |
