>>28506441 (OP)No, but I've been thinking about tinkering my car to add that feature. I just dont know enough about car systems yet to understand whether/if I can add an older junkyard radar + acc system that hooks to throttle or something. And what sort of knowledge is required for that to be. With a computer at home, I know everything how to add parts, upgrade parts, add third party extra stuff and software for it, but cars are bit blackbox since its maintained by non-computer forks and information about the vehicles arent disseminated on the web.
