Most of this stuff comes as an integral part of the latest engine management systems that the manufacturers source from Bosch and Marelli et al. In Europe you even get ESP/TC BAS/ABS on 70 HP superminis. It effectively costs very little for the manufacturer to implement and fills out the spec sheet very nicely. It undoubtedly saves lives but I think it gives people a false sense of security. It can save people from situations they should never have got into in the first place, and they won't even be aware that it happened.
