He had a slight skid/slide in the right-hander, before losing it on the left-hander. Looked a bit too fast, as well.
Yes but, as I saw it (which is admittedly not well, because of the schizophrenic camera work and editing) he was either totally off the apex (and line) for the right hander, or was so massively late for the apex that the little skid was the result of trying (too late) to get back to the line and set himself up for the left-hander.
The little skid just set the stage for the big skid. As a professional race driver and instructor expressed it once, many years ago, tires have a fixed amount of friction to apply to the road. Whatever it is for that tire, it's 100%. That 100 percent can be used for accelerattion, deceleration, and/or cornering, but the total can never exceed 100 percent. So if you're using 75 percent to go around the corner, you ONLY have 25 percent left for braking. Try to use 26 percent for braking, and off you go.
Once the tires break traction, you MUST slow down (or straighten out) in order to regain traction. This is best seen at drag races. The death knell for a good run is "going up in smoke" off the starting line, because once you break traction you have to let off the gas to "hook up" again.
Back to Hammond: At 0:07 in the video, he was on the left side of the road with his front wheels still turned right, when he should have been on the right side (or in the center) of the road and already turning left into the apex of the left-hander. He was fooked basically from about 0:05 on ... or before.
