Hello, Lexey, you wrote: G>> Accordingly drivers who reduce speed - good, suitable drivers. L> this output is justified by nothing. It is justified. The probability theory. Any trip at the wheel can end with failure. Not important on whose fault. It is possible to be the megaabrupt driver, but to catch on a route because of the traffic which has burst at another participant of a wheel. And to catch in a situation when chances to evade are not present any, be you though 10 times the racer of the formula one. Them too it is regular from safety frames "cut", if that. During a rain visibility, the review in side mirrors is reduced, the brake way etc., and, hence, increases the probability of road accident considerably increases at all participants of traffic. At the beginner, the first time sat down for a wheel, it with, we admit (digits are made up), 1 % on 1000 km to 5 %, at real "pro" with experience, skills of extremal driving etc. - from 0.01 % to 0.03 %. But at all. A real method to lower probability of road accident in a situation when it is impossible to affect other drivers, there is only one - to give to itself(himself) to more time for response. To reach it it is possible: 1. Possibility to manoeuvre, brake etc. 2 was magnification of a distance to other machines of a flow that if they start to do something not that. Lowering of speed that time for response, besides, increased, and, in case of road accident, consequences were less heavy. E = mV^2/2 still nobody cancelled. 3. Increase of the general vigilance, type "to twist a head on 360 degrees" and to start to count other drivers not on 1-2, and on 2-3 steps forward. All. Personally I do not know other methods. From this it follows that drivers who during a rain reduce speed, fulfill, at least, one of the enumerated recommendations, and try to lower the probability which has increased because of weather conditions of road accident. So are good and suitable drivers.
