Mathieu told me that it was reassuring to see the blind spot symbol illuminate as he drove past motorists during his motorway commute.
"I know they can see me and won't suddenly move out in front of me," he said.
I mentioned my appreciation of blind spot monitoring to a motoring colleague, who lambasted my comment.
"If you set your side mirrors correctly and have the curved ones that cover more area, then you don't need blind spot monitoring," he said.
Haters be hatin', but the safety device works both ways: assistance for motorists who have it and reassurance for others on our roads.
