Carol’s car surges and gets bad gas mileage. Her mechanic says the problem is that three different people drive the car--Carol, her husband, and their teenager, so the car’s computer needs to adjust to the different driving styles. Is this bogus? Tom and Ray say there may be some truth to this theory, since the problem stops if Carol drives the car for a few days in a row. The shift pattern may change for each driver.
