I almost never purchase the extra "full coverage" insurance when I rent a car, because -- well, because I'm cheap. But because I had left my regular proof-of-insurance card at home -- and, yeah, because someone else was paying for the trip -- I agreed to the additional coverage when I rented from Budget in L.A. this week.Well, I don't know if God or Truffaut or Elvis was looking out for me, but I made the right move: The very next day, while heading back to my hotel after attending a screening at Lionsgate, I was driving along 405 South, having just entered from 10 East, when a truck veered into my lane and... Well, let's just say that, hours later, I found that I still had tiny bits of shattered safety glass in my hair. But, what the hell, I was still alive. And, not incidentally, I also had another rental car to drive.
