Indeed. That kind of stuff is scary. HAHA.
I do wonder though, how much of that could be avoided if you could wash the underside of the car somewhat frequently.
It would help, especially if one had the chance to
heavily, even excessively Fluid Film, undercoat, or whatever the whole underside after said washing.
But especially this winter season so far, the effing car murdering salt soup has been cruelly relentless.
The various state and local DOTs throw down millions of tons of salt and brine, even when it does not warrant it even for the lowest tire 'common denominators'.
Then it stays dry and well sub-freezing until the next big snow/ice dump, so there is no rain to wash all of that shit away, but the sun and some near freezing rises in temps melts the piles of snow/ice into runoff, which then activates the caked on salt to do it's unibody/subframe/suspension obliterating stuff when unavoidably driving through it (it usually runs totally across the roads at that point).
IF I could afford it, or had a place to park it without being towed, I would consider a total winter beater to try and save this car, even more so if I could keep it in an enclosed garage.
