I think any driver who consistently beats Ferrari, race after race, championship after championship stands a chance of being booed by the manu fans of the F1 world. Vettel made a bad call when disobeying team orders but the end result was of little effect and it's now long, long gone. The guy doesn't seem any worse as a human being than most of the F1 drivers and seems more palatable than, for example, the consistently pre-menstrual Hamilton.
