But for all that, the car has five separate computer systems (running Windows 98, by the way),
No, no ,no, no, no (one no for each computer).
Actually, think about this; if this car is running 5 copies of Windows 98, there's little chance of it actually making it out of the garage. Hence, calling it a 'Safety' car is technically correct, since the only crash it's ever going to encounter is a system one.
