While I do absolutely understand your point (and agree with you) that’s not always going to happen. Some people can’t afford to miss work for example, or would get fired for calling out/being late for the tire. I don’t necessarily blame those particular people as the deeper problem is a society in which we we’re living week to week to get buy and risk losing much if not all if even a portion of that weekly pay doesn’t come in.
Also blame employers that pay diddly and are so quick to fire people. They place profit over human life and that’s no better.
I wouldn’t drive with issues like that, but then again 1: I know cars and work on my own stuff and 2: I can afford to miss a day of work every now and then.
So while I agree and don’t support people driving cars with dangerous issues, I also understand that some people are so desperate that it’s not really an option, also a mechanic isn’t cheap and people don’t much help others nowadays.
