Ever since Diana Spencer's death in Paris, and it was discovered that the limousine driver, was drunk.

While this has been disputed, nonetheless, it impacted me, and I avoid situations that I do not know who is driving.
Now, I don't know if the driver in this situation was drunk, nor am I insinuating this. Just my own neurotic preference to not get in cars with drivers I do not know personally. This was further reinforced by a most unusual situation with an Uber driver, who...let's just say, 10 minutes into the ride, I asked to get out.
Sad situation. Because, of course, no one wants to wear seatbelts and ruin fancy clothes. This has not been verified yet though.
