1. I believe that all school buses are made by the same company, Maybe not. But at any rate, here is how our school buses work.
There is a radio in it and the bus driver radios in. Now I would think that it would have 911 capabilities in it also, but I do not know that. I would like to make Google my friend, but I just have time to type my thoughts here right now.
2. The white truck-granted I live in the country where I live, so I don't have that much experience, but I have never seen a car hauled off for mechanical problems.
Even my almost 10 year old Honda has sensors that give warnings that something is going wrong with my car.
Over the 40 years of owning cars and we were poor and young, I never had a car die in the driveway. On the road, yes. Somewhere else, yes.
But it was no surprise, even before the days of sensors. I was just praying the car would keep going before it died .
Most mechanical things in a car give warning before they go. Your starter doesn't usually just quit one day. It does erratic stuff. Same with the water pump.
Struts, shocks, engine. There are signs, some louder than others.
I've never had A/C so I don't know.
With the father being an engineer, I would think that he would be more sensitive to the signs than I am and would bring a car in before it comes to the point that it needs to be flat bedded to a dealer.
But, I am no mechanic.
My son is an engineer and my hubby used to work on cars (ours and friends, out of the goodness of his heart). So, I've had a LOT of car discussions especially since we try to keep them going as long as we can.
