When I had my blowout this past week, my brother (who also has a 5ver) was teasing me for having spent the money on the pressure monitoring system. However, no tpms will catch an instant blowout. It will however, catch the leaks between trailer rest stops. I definitely have peace of mind knowing what my tires are doing.
Speaking of safety at roadside, I just about hit a woman yesterday on the highway near Syracuse. She pulled off the highway onto the shoulder and jumped out of the cab of her pickup without looking. I was blocked from moving over to give her space. I think I aged her a few years.
