Welp. Looks like Shanghai channeled their inner Bobby Epstein and found a new, different way to cheap out on the track surface.
The story behind Shanghai's 'painted' F1 track surprise: https://www.motorsport.com/f1/news/the-story-behind-shanghais-painted-f1-track-surprise/10600016/
They do this nonsense on our neighborhood streets here in Austin. It only lasts a couple of years and wears through even with that limited amount of very slow-speed, residential traffic. Imagine what it it'll do on a racetrack.
If it's as durable as the crappy street surface in front of my house that's constantly littered with loose, tiny rocks that have worn off, then yeah, the track will wear away and grip levels will vary during the weekend. Not as bad as COTA's varying grip levels throughout the track, I'm guessing, but probably still significant. But as Kimi says, it's the same for everyone, so wewillsee.
