John259 is 100% correct. The difference with electric bikes is that you would go under the radar for a lot longer and a residential private track would be basically unknown unless you could see it.
But if it was a public track or training facility, eventually the people would see traffic...
I watched him do that start a few times, was hilarious to watch. Hands/Team Latvia were pitted right next to the practice start area so I hung over there a bunch pestering them LOL.
How was the GP condition-wise? One year I was there it was like epic conditions, perfect dirt. Couple other times really bad dust.
Kinda sucks they didn't add any of the pro sections for the MX. When I saw that they ran it for 2021 it almost motivated me to go!
Last year they ran an interesting combo layout where you skipped the quad, then did the pro section, but then cut across and did not do the whole big downhill.
Keep in mind they don't run the big quad jump. You go through the dip, then hook a left at the big quad landing and go down the hill.
GP could be nice this year with all the recent rain, but then forecasted nice weather for the weekend.
