We finally had a rainy spell this winter during our drought here in California. One morning the car actually slipped pretty severely! The road situation was actually very extreme. I was driving on a very unusual pavement where half the roadway was a large grate — probably five feet in length. So two of my wheels were on wet slick pavement and the other two were traversing this highly unusual grate. For a brief instant the car definitely swerved and scared me a bit but the quickly corrected itself as nothing had happened. I rarely actually take this particular section of road, but I vaguely remember it being dicey in the past. I suspect this unusual grate was installed to correct severe flooding problems.
Late last year we had a serious cold snap and the garage one morning was around 40 degrees Fahrenheit (about 5 degrees Celsius). To my surprise, I actually had a dashed yellow line — limiting regen. While parked the car uses as little energy as possible to keep the battery warm in order to avoid the energy wasting vampire drain. In cold weather you can drive your car with a cold battery, but the regeneration of energy into the battery is limited. After only a couple of miles of driving, the battery warmed up and the yellow line disappeared.
As I earlier reported, I did a number of supercharger tests where I drained my battery down to 0 rated range. While intentionally draining the battery, the upper limit of power was reduced — indicated by the dashed yellow line. I don’t remember the exact rated range left before the power was limited but it was at a significantly lower level than normal. The car still had enough pep to very comfortably drive.
I also noticed in the rain serious impact to the rear facing camera. I think this is a problem with all cars. I had grown a little too dependent on the camera during driving instead of the traditional mirrors and head turning.
