The cars were hauling ass coming straight toward me entering the hairpin turn then heading camera-left. These two cars were likely about 3-4 car lengths apart so the lead car was already heading left fast while the trailing car was still pointed straight toward me.
My shutter speed was kinda low: 1/160th. My back-of-envelope estimate suggests that at 1/160th of a second, the lead car would move about 2.5 cm if it was going about 30 Km/h relative to me at 45 degrees into that turn. If the lateral smearing of the license plate is to be believed, that agrees and is about right. I was lucky to have anything in focus at all. I had no tripod or monopod, too low shutter speed, and there wasn't anything obvious to manually focus on at that low angle parallel to the road surface. I braced the hood against the chain link fence for stability and focussed on what I hoped were tire marks in the middle of the track. I should have maintained the shutter at 1/250th or faster to stop the lateral movement I think. I could have traded-off higher ISO to get that. My entire catch was comprised of near-misses I think.
