I'm glad to be working from home, but the school run twice a day is starting to bite.
We probably do less driving than 80% of families though, our mortgage is small now so the interest rates aren't a huge problem. Plenty of people are going to get wrecked here, particularly the working poor with long commutes.
If we start seeing logistics gridlocks the big one is going to be medication. Insulin, asthma inhalers, if they're not on the shelf at the chemist, people die; and the prescription limitations mean stockpiling often isn't an option, so people don't have a heap of spares. Anti-psychotics are distributed 1 week's worth at a time; so if they're held up a month, things are going to look real Mad Max real quick.
