Just as an example: my current car has a very distracting audible and visual warning when it detects ice on the road. The problem is: this warning delivers 99% false positives (in fact, it seems to be triggered simply by the thermometer crossing a temperature threshold (3C), in either direction). So - yes - it is a dangerous distraction. However, if the manufacturer had actually gotten it right, it would have been very valuable.
Opel/Vauxhall or other GM brand?
I alweays had the feeling the engineers only included this because they could add another feature to the ads without adding any new hardware. There is no use in a warning light if it becomes NORMAL between November and Febuary. THANK YOU, I KNOW IT'S WINTER!
