For comparison the ID4 had 0 failures at this age for this category, and for a much larger sample size.
I assume these are all taxis as they're being tested so early. This implies there a ton of unsafe privately owned Model Ys on the road.
I'm not sure what the vehicle safety and equipment failures would be, nor the distinction between lights and lighting and electrical. The fact that it's a noticable failure point is a little surprising to me because all the lights should be LED and pretty solid.
(Though, I'll say, even though we have mandatory inspections, 5-10% of cars in my area are driving with at least one light that's out.)
They shouldn't fall out of alignment that quickly so I'd guess they're poorly aligned from the factory
I once had a Fiat Panda from 1984, 20 years old by then. It had a small checkup and maintenance, then went for the inspection. It passed, but was highlighted for inspection from the controlling organizing. The mechanic, owner of the shop, started getting really nervous about losing his license, asking, is the car allright, is it really allright? And it passed inspection again.
Anecdotally most people I know here don't bother with preinspection. It's usually cheaper even if it fails the first time. Although looking at the data most people driving EVs could probably save time/money by investing in a tire thread guage!
