yea.... it's definantly all ice!!
The way the cars slide & accelerate as they are sliding sideways means it was
1- all ice
2- slopes down
there isn't a set of street tires that would get traction unless you are on snow/ice tires
which reminds me, I need to throw them on my viggen tomorrow
& I forgot to mention their climate is similar to Seattle where the ocean keept the city at warmer temps then just a few miles inland. Rarely ever get snow/ice
