I overheard a co-worker say this, “If you are ever driving and your brakes don’t work just pull the emergency brake.” Both myself and another peron yelled,”NO!” After the shift they were outside on a cold night revving there slant-6 valiant of the 1970 variety to full red line right after it started. I asked them, “Did the same person who told you about the emergency brake tell you how to warm up your car?” “Why yes” was their reply.
