I was driving home a few nights ago on the highway, it was snowing lightly, roads wet, slippery, on autopilot. A car merging on to the highway too aggressively lost control and spun out, darting left across lanes of traffic...a car to my right made an impressive controlled maneuver to avoid the car and I habitually tapped the brakes, took control of the wheel, trying to slow down and give space as well and we avoided the collision. My question though is this.... should I try to keep the car in autopilot when I see something like this unfolding in front of me? Will the car do a better job staying in control and avoiding the accident? I realize there might be times when I don't have time to react but this was like slow motion, could see it all playing out, we thought for sure we were crashing and I habitually took over to avoid. It was the closest call I've had in awhile and while we avoided it all I just can't stop thinking about whether I made the right call in touching that brake pedal and taking over??
