MADISON, Wis. — Since last summer, automakers in Detroit have been losing sleep over two vexing issues: Over-the-Air (OTA) software/firmware updates and cyber-security for connected cars.
First, OTA is a big unknown to carmakers who have traditionally depended on service visits to dealerships for software updates. Only a few automakers have OTA update capabilities, and only Tesla can remotely update all safety-critical systems on its entire fleet.
