Looks like many of these were caused by somebody trying to be nice and waving someone through in front of them.
Then they cross the adjoining lane and are t boned.
Always follow the rules, never wave someone across in front of you, or let someone wave you across.
It's a recipe for a wreck!
They may think that they are being nice or considerate, but when you get t boned, they won't be telling your insurance company or the judge that they actually caused the wreck.
They will be nowhere to be seen!
