Pretty good stuff!
Did you try some runs with fewer shifts? Seems like you were going back and forth really fast in some sections. Did you try leaving it in gear?
And yeah, wipers are no big deal. Happens to a lot, especially with a lever position like our cars. Had a Lotus Exige at the course this weekend that kept getting it's horn blown. Kept corner workers on their toes. Including myself...
PS: No slaloms?
