It’s crazy. How do we even allow selling cars without HEPA filters.

One of the reasons I wrote the comment above is because my filter has worn out and needs replacing, so all of a sudden I can smell all this nonsense again.
1000% with the money.
If the exhaust had to go through the cabin so the driver got the worst of it, car exhaust would be the cleanest air on the planet within months and/or alternatives to cars would rocket.
But as long as it’s other peoples health affected, meh.
This is why forklift trucks and Zambonis run on propane instead of petrol or diesel. If you burn gas, you get no carbon monoxide or unburnt fuel because it runs ever so slightly lean and all the fuel is burnt.
This means keeping the air clear is just a case of getting rid of carbon dioxide and water, so you can open some vents (warehouses have great big vents, big enough for trucks to drive in and out...) and let the place air out. You won't die if you breathe it, unlike the CO and unburnt fuel from petrol and diesel engines.
It's a simple and inexpensive conversion, too.
(Edited to add) Hmm actually people are already doing LPG conversions today as it's cheaper. Not sure if all LPGs are as pollution free, though.
You can get ones with a complete set of LPG injectors and an ECU that takes its timing from the petrol injectors, and these are incredibly efficient. They're a bit harder to install (you need to drill holes in the intake manifold, it's a faff) but the engine can be mapped for even more power than on petrol and a tiny amount of pollution.
There's still a lot of CO2 and water vapour, but as previously discussed you're burning all this shit anyway so you might as well extract useful work from it.
The time to have done this was 25 or 30 years ago, when it was ridiculously cheap to buy gas and there were a lot of old-fashioned carburettor-fed cars that were incredibly badly polluting.
