Road surface and consequently traction can vary (for example, gravel). It's important to stay well within margin. Once you lose traction at speed, it can be hard to get it back.
TL;DR take it to the track, where the road surface is well maintained.
Technically yes but on any given track day there can still be gravel, weeds, rubber, bits of material from car body kits/aero, and even various liquids that have leaked.
