Hello, you can use the maxSpeed attribute to achieve the desired effect. The formula 'accel*(1-speed/maxSpeed)' is no longer used to compute acceleration. Vehicles accelerate using their 'accel' attribute regardless of current speed. The specification page was outdated and is now fixed. regards, Jakob
