Lotta wrecks due to SMOKE, as well dirty interior windows.
Rather weird People can't LOOK FORWARD as well both SIDES, as in literally SCANNING the future for any potential PROBLEMS. At night, of course, it's rather difficult except in well lit areas.
HAZE at night, surprised to not read about any ACCIDENTS/WRECKS due to it, or it'll be very soon.

Used to be some collisions/wrecks in the mid to latter '70's, southern Cali, due to interior smoke (yo, holmes, think Up In Smoke).
