Cars at the crossroads

This game is about intersections. There are no traffic lights, the cars go straight ahead. You need to stop them or speed them up - so you will avoid accidents. Gradually the cars start to go faster and faster and there are more and more of them. Also watch out for trains. The game has 3 different levels - a small town, a large metropolis with a railroad crossing and the countryside. You can customize the initial speed of cars and the frequency of their appearance on the roads. There is a leaderboard - the longer you last and the harder the game is, the more points you get.Cars must not collide with each other or with trains.
