My condolences Evo - I'd missed this thread till now. Sorry to hear this story, it's very sad. He sounds like he was a fantastic boss and a great mentor. All the best to his family and friends over the tough months and years ahead.
I think we all need a reminder every now and then, to back off and take it easy on the roads. I know I'll certainly be more mindful now.
Thanks for sharing your story, though no doubt it still pains you to talk about it.
