The motorist is approaching the decelerator. The speed is brisk, certainly above the permissible limit of 30 kilometers per hour. Just in front of the decelerator, the driver turns the steering wheel suddenly. The bow of the car hooks to the left, the tires do not hit the decelerator. Yet a quick change back to the driving line before the oncoming lane deceleration, and the journey can continue.

Such situations have become commonplace on Hämeenkyläntie after the installation of a “sledding lure” as a slowdown, says a reader who has contacted HS Espoo. The observation of the afternoon traffic confirms the reader's observations. The driving performance of the wildest drivers would be better suited to the formula track than in an agglomeration.

The problem is clear. In front of the Lintuvaara school stop, two decelerators have been installed, one for each lane. There is just enough space between them that dodging the retarder to the second lane is effortless. What makes the situation even more dangerous is that there is a protective road between the retarders.

The retarders, commonly referred to as cushion retarders, are installed in parallel so that they cannot be avoided in another lane. The advantage of pillow decelerators is the softness of the ride. For example, buses get over the retarders more smoothly than many other retarder models.

An explanation for why the retarders are installed in this way cannot be found in the city during the deepest holiday season. However, it is confirmed from the Urban Transport Unit that the residents have sent feedback on the matter. So the city is aware of the problem of retarders, but what can be done will only become clear later.
