Even modern cars pollute a lot (especially in winter) because you need a certain temperature for the cats to start working. On short city trips it happens frequently that you never reach proper operating temperatures.
Yes, any cyclist daring to drive in winter can easily confirm this. It is so disgusting (and unhealthy) having to stand behind a ICE car on a traffic light and being behind a electric car is such a relief, that thoughts of wishing to ban all ICE cars as soon as possible (at least in cities) come automatically.
I used to work for the Air Resources Board of California, and while there is a warm-up period, modern ice cars are so profoundly cleaner than cars even from the early 2000s. It’s pretty stunning.
Regardless, there’s nothing cleaner than no combustion, and I can’t wait until EV‘s have replaced them all
