ah snap! I was wrong. Driving is not safe at idle as well! So I should rephrase: A running car is never safe.

It is also beneficial because various crap gets delivered, people move fast to where they are needed and generally stuff gets done. Some paramedics even get so brazen as to fly helicopters to the rescue.

How do you draw the line?

It's not about drawing the line, it's about quantification the impact.

I think this is what people don't get about the study. The study is not saying no one should drink. It's not saying that the risks of drinking outweigh the benefit. It's saying that for any amount of alcohol, ingesting it, on aggregate, decreases life expectancy. Nothing more. It's a measurement of the increase of risk, which can then be combined and contrasted with other measurements and help make informed decisions.

You draw the line however you want. You now have more information to make that decision.

and according to the WHO one particulate from that exhaust increases your risk from pollution above absolute zero, hence driving is not safe when it comes to your health.

What if you drive a Tesla?

Teslas still have a crash risk, emit noise and dust locally and emissions remotely.

Tire particulate is a particularly nasty form of pollution that most are unaware of. EVs aren't particularly better at reducing tread wear (some say it's a bit higher due to instant-torque at 0 RPM).
