This happened in Toronto ten years ago.
Within a short time, several friends received tickets (warnings) for excess speed on the highway. Moreover, although the excesses were insignificant, about 10-15 km per hour, drivers were punished strictly - in addition to monetary fines, they received punitive points, which automatically entail a significant increase in insurance.
The penalty was double offensive, because the usual flow of cars on the highway with a speed limit of 100 km per hour runs 120-130 km per hour, at least in the left extreme row.
The offended drivers decided to take revenge for such undeserved harsh punishment. In order to do this, they, invoking the help of friends, did the following.
On one of the summer holidays, when the people full-fledged drive cars out of the city to rest, our heroes, each in their car, went to the most "densely populated" highway and, being in a row so as to fence the entire highway, began to drive on it with the maximum permitted speed of 100 km per hour. Neither more nor less.
As a result, behind our avengers, a giant traffic jams of evil Canadians were formed, rushing faster to come to the bosom of nature, which was even shown from a helicopter on the news.
All this was not left out of the attention of the local police, which made an unfair, but the only correct decision - to detain friends, and to allow traffic jams, in the absence of interference, to dissolve themselves, even at prohibited speeds.
The detainees were fined for interfering with the movement of other vehicles. But this time friends, I feel my full right, went to court, which, of course, won entirely - you can not be punished for the implementation of the rules of movement!
The results of the fight for justice were such. Police gave unofficial advice not to stop cars driving on highway at 120 km/h in the general stream, but ordered more attention to drivers with aggressive driving or driving from 130 and above.
Justice has won.
