I need a new Electronics project (or prodduct so I can quit the day job and work for myself...) and was thinking about designing something for use in a car and/or motorbike. Has anybody got any suggestions of things they'd like to have? OK, that is a very open-ended question but it would be interesting to hear if there is anything that hasn't been done or could be greatly improved that people would like.
Ideas so far have included various sensors (wideband O2 etc) with a display, some sort of ODB2 data logger, speedo corrector....
