Re: Not my fault guv...
being a tech website, I reckon a large proportion of commentards are predisposed to identify glitches and bugs, it's how we make our money, whether directly or indirectly.
As a rule of thumb, if it's new, and not run in, there's probably something wrong with it somewhere, it's just a matter of finding the symptoms.
For this - as others have said - without a control group, it's impossible to say whether the reported shunts are a indicator of a problem or not.
If there is a problem with chocmobiles being shuntmagnets, it's likely more to do with the kind of signalling we all do inadvertently - road positioning, pre-turn wobbles, unneccessary braking etc. These give other road users information about us as drivers. If a googlecar gives contradictory signals, or none, then shunts may occur more often as people misread what the car's about to do.
