Sorry to hear about the damage, glad to hear you weren’t hurt…
The lot in Bowie has had incidents like this regularly for years. I've looked at the problem of accessing the lower lot safely and to the disappointment of a lot of drivers; I’ve concluded it can’t be done.
SCCA safety rules are an excellent base line for autocross course design, common sense is equally important. Running a performance driving course through hard obstacles 25 feet apart doesn’t pass either standard.
A lot of clubs use the lot in Bowie but only one I know of, doesn't use the lower lot.
