Question

Driving would be more pleasant if we didn't have to put up with the bad habits of other drivers. A newspaper reported the results of a Valvoline Oil Company survey of 500 drivers in which the drivers marked their complaints about other drivers. The top complaints turned out to be tailgating, marked by 23% of the respondents; not using turn signals, marked by 18%; being cut off, marked by 14%; other drivers driving too slowly, marked by 10%; and other drivers being inconsiderate marked by 6%.
