Maximum speed with consequences

Hello everyone, I tested the top speed on a free, three-lane track with my A3 2.0 l TDI and could see that only one stroke before 240 was finished on the speedometer. I don’t know how high the actual speed was, at least much more than the manufacturer’s specification. I then took the foot off the gas and let the car roll out. It took a relatively long time until 120 and 100 km/h were reached again. e between 160 and 180 km/h and had to do a full braking, i.e. I have passed the brake pedal with full force. At “239” on the speedometer, no full braking would protect me from an accident, if one would drive out from me or change into my driving lane. This test made me very thoughtful and I visited the next stop very close by. Just by chance I meet a computer science teacher here with a new A3 3-T And he spontaneously asks me if I had not been flashed, because on this route the speed was limited to 130 and his MMI would have warned him of the speed camera. I was shocked at first and would certainly not have driven there so fast if I had seen the border signs. I also did not notice a speed camera, but I also concentrated on driving and driving ahead. Nevertheless, I had plötzli When I thought about the consequences and consequences, I asked him how or how his MMI would warn him of speed cameras, because according to my knowledge this was not permitted. He looked at me grinningly, but did not provide any information. I am familiar with speed camera alarms on smartphones and I asked for them again. He would have talked about the MMI and not about smartphone apps. I did not receive a further answer. I hope that it will not happen. What would you do in such a case? And my second question is addressed to the technically versed ones among you: Can the MMI warn against lightning, if necessary be modified accordingly? Friendly greetings Audire
