True...but I barely drive my car its been 7 years and 52k thats about 7.4k miles a year. Those few minutes lets say 30 min times 2 a day is an hour times a week 1 times 7 hours times 4 for a month is 28 hours times 4-5 months is 112-140 hours of unnecessary movement for your water pump. This is an estimate could be more or less.
