Re: Well, I can name one that cost a fortune to fix
A guy I know worked for a major car company and they had a similar issue, some absolute idiot at an outsourced agency had got a mix of units (km & miles) in use (probably did not even drive) and it was not discovered until cars were in the showroom and being sold. Result was a very expensive recall for firmware to be fixed given the legal implications of telling a driver the were only doing 50 (mph) in an 80 (km/h) zone so they had a another 30 to go if they wanted.
