I can totally relate to having car troubles and honestly, shit happens. However, just as you're saying, I actually started thinking about how things could have been worse.
My friend in the driver's seat at the time could have accidentally killed somebody or crashed into a wall if there wasn't a concrete pole in the way.
Anyway, for a couple of days that the car was at the mechanic, I started using my bicycle and that's good for my health.
It's a good thing no deaths were involved and the only thing that got banged up badly was the car.
Bicycles are a great way to get around and roaming on foot is probably the last resort, but thankfully that was working out quite well for me.
