Looks like she had started to enter the tunnel before you got to the approach. Why so close to the tunnel entrance when you can see her coming through? Looking forward to the dash cam footage.
I'm thinking of buying this car from a car dealer so i assume the vehicle is now sold by the driver in question, In your opinion was the driving style of the driver likely to have excessively affected the vehicle.
She's clearly in the tunnel BEFORE you get to the sign.
Unless of course your footage proves otherwise? I doubt it though, that's why it's not being posted.
