> is the difference expensive equipment vs human lives?
The difference is in safety margins. You really shouldn't drive a vehicle to within 2cm of any object on public streets. Not even while parking. 0.5m (2ft) is about the closest you should ever drive your car to anything really.
Whereas for a tractor getting within 2cm is normal operating procedure. You won't be able to grab a 500kg (1100lb) attachment and drag it over to your tractor because you stopped too far away.
