Well I installed my dash cam awhile ago.
On my way home from my grandfathers, after taking down some ladders, dressers, my Toolbox and tailgate for storage. (had a utility trailer) I was driving I could see a ambulance do a U turn across the median. Well I found out about a minute later why, Im assuming the car Hydroplaned at about 60-75mph/100-115kph went off the road and rolled over a few times.
I hydroplaned a few times, Im pretty sure the trailer was the entire time back. It was raining super hard.

 

What kind of dashcam and how much?

 

It would be cool to keep a dash-cam that keeps the speedometer in view. That way if you get pulled over for a speeding ticket you can dispute it

 

I paid around $40 shipped with no Micro SD Card.
I bought a 16gb Card, I also have the Audio turned off, and it set to "HD" which isnt truely HD lol
