I wouldn't trust any slot car manufacturer to be accurate in this respect. I am also intrigued to know why, in the real world, it is necessary to identify which side is which. How would it make any difference and in what way would each side's tyres vary? There are left and right hand corners on all normal circuits so surely both sides need to be the same.

NASCAR and Indycar are, of course, different as banked curves need special set ups with different pressures on each side. Martin Truex  found this out to his cost a few years back when his team got them mixed up in the final race and he had a car which which wanted to turn right instead of left and it ultimately cost him a championship.
