hmm... well there was the one that actually resulted in a collision. The blow out while braking while driving my '75 maverick that I related before so I won't bore everyone with it again.
The most recent was jan. 2005 when I was on I294.... Shortly after the TW car had been smashed. I was no longer used to driving the mustang on snow. On top of that the tires weren't exactly up to the task, but I had not planned on driving it in snow. Usual poor butt plowing, right lane was basically untouched. I am getting close to my exit so I carefully move the mustang into the right lane after having slowed. The rear end doesn't like this and starts to come around. I catch it, it oscillates the other way, I catch it, this keeps repeating when the sleep driver who was behind me in the middle lane decides this is a good time to pbutt me while hugging the lane line. I can understand wanting to pbutt, but why so close? The left lane was open and clear. I catch the oscillation and avoid hitting him. How he couldn't see the oscillations was beyond me. The semi driver in the right lane behind me noticed and slowed way down putting a lot more distance between us than the generous distance I had given initially.
After way too many oscillations I get it calm down and exit. Thankfully the standard winter driving techniques worked. I had been very gentle but the corrections were even causing problems.
