They are not invisible walls, but there are bugs indeed.
Anyway with drivers testing for 2 weeks, it should not be an issue to avoid the walls, it wasn't for me at least.
This track was chosen because we'd been using the same track for about 10 years it seems. Our track team tried their best to fix the guardrails but due to time limits, some bugs were still there.
Congrats to Pat for his pole, hopefully he can get a good result as well.
