I spent a few years as a design lead on autonomous driving for Android Auto, then spent my weekends in a 27-year-old car doing the exact opposite. Drive came out of that gap. It turns the phone already in your car into a telemetry rig — g-force, braking, cornering, the whole trace. It also flags license plate reader cameras as you approach them, since I like my privacy. No wiring loom. No dongle. No laptop. No sign up. Just driving fun.
