Why harsh braking hurts your score more than speeding

Every trip on MotoRoadies is scored out of 100 from four inputs: harsh braking, harsh acceleration, fast cornering, and over-speeding. Riders often assume speed drives the score the most — but in practice, braking severity carries the heaviest weight, and here's why.

The physics behind the weighting

A hard brake at any speed indicates a late reaction to something in the road ahead — traffic, a pothole, a distracted pedestrian. It's the clearest single signal of a near-miss the sensors can capture, which is why it's weighted more heavily than a smooth, sustained higher cruising speed on an open highway.

Over-speeding matters too, but a rider who holds a slightly elevated, steady speed on a clear road is statistically safer than one who's constantly overshooting and stabbing the brakes to correct.

What actually moves your number

In our internal analysis of the last 90 days of trips, the average score gap between the top 10% of riders and the bottom 10% was almost entirely explained by braking events per 100 km — not top speed. Smoothness beats speed, every time.

Takeaway: read the road two seconds further ahead than feels necessary. It's the single cheapest way to raise your score.
