Yeah, probably the sealant on the garage floor, and if the surface is smooth, as opposed to grooved, that might contribute as well.
At least one of the parking garages I worked in Downtown, many years ago, would have that occur.
Another fun thing was when there was snow, and people would have the cable chains on their tires. The last location I worked, the cashier booth was right where the exit ramp from the garage began it’s incline. So, when customers stopped to pay, typically the front wheels would be on the incline, back wheels still on the flat.
It was a bit annoying, yet at the same time a bit comical, to have the customer start pulling away after paying, and the tires would be spinning, grabbing very little, and sparking!
This would also happen as they drove up the ramps from the lower floors, but not neccesarily to the extent as the one at the booth, because coming up from the lower floors, they’d usually have a fair amount of momentum already.
It was a good way to alert me that somebody was on their way up! ;-)
