You don't seriously think its safer for blind car owners to drive around on incorrectly inflated tyres, do you? Running tyres at the wrong pressure can adversely affect vehicle handling, putting other road users at risk.
Even if you're not sharing the road with them, think of the environmental impact of all those tyres being prematurely replaced due to accelerated damage, or the increased fuel burn required to propel a car when they're under-inflated.
Honestly... Some people are so narrow minded.
