I'd imagine the concern is the radioactive dust / fallout getting stuck onto the vehicle, clothes, and hair which would increase your exposure time; getting through that zone as quick as possible could limit that dust sticking. But that's just my guess.
This is the problem. It's not just being in the area, it's inhalation/ingestion and direct exposure to radioactive dust. If you look at [https://www.dhs.gov/sites/default/files/publications/Quick%2...], the levels just from increased radiation from a single detonation there are certainly not fatal in a few minutes, but with multiple detonations it's not difficult to get a lethal dose in a few or hours or a day or two. Couple that with the inhalation/contamination issue, and yeah, be afraid.
If I saw that sign I'd be a hell of a lot more concerned than "oh, miniscule cancer risk later in life, meh, I guess I'll just slowboat this one".
changing engine and cabin air filters would become an extremely hazardous affair
