When driving, what is the average reaction time?

I just bought an electric car, but I was concerned about the conditions at one of my local charging stations. There is no cover over the station, so my car is exposed to full sun while charging, and I live in a place with very hot summers. Is it OK to charge electric cars under heavy sun?

I’m trying to get my car started for my morning commute but my car has trouble starting in freezing temperatures as it’s an older vehicle. Starter fluid usually does the trick, but I’ve run out. I’ve heard that you can use brake cleaner as a starter fluid substitute—is this true?

I’m having problems with my emergency brake. It seems like it’s stuck, so I’m worried I may have pulled it too hard or something. I hate having to take my car in for maintenance, since it’s always expensive. How much will it cost to fix my emergency brake?
