That is also part of the cascade. Quality has dropped off, while the ability to repair them has become more difficult. You have less and less mechanics able to work on vehicles due to stringent systems being put into place that prevents anybody, other than the companies, from being able to work on them.
Families will no longer be able to afford to purchase, insure, and maintain two vehicles. This of course drastically cuts into sales, which then decreases manufacturing which leads to companies going bankrupt.
The next five years is going to be a ride...
