Hello, for a long time I have installed a Dashcam in my two cars at the front and at the back. Several times the photos were very helpful (e.g. in case of uninflicted accidents or in case of coercion and insults by other road users). Now I am also looking for a driving style sensor, similar to the sensors that are installed in the telematics tariffs. The sensor should register when abrupt braking and driving movers are carried out. ? I know that there are such devices to buy, but I did not find them myself.
