So your system knows the exact situation and still is slowing down my bike, just at the moment I need to accelerate to avoid being overrun by that large truck heading into me.

After reading the article, it seems like the system is supposed to temporarily jam pedal assist, turning your ebike into a regular bike. And the system would need to be installed in all street legal ebikes for that to happen. Since you’re still free to accelerate by pedaling like a normal bike user, that significantly reduces the amount of situations where the pedal assist would actually save you. If you can’t avoid collision by pedaling harder, you probably had no chance in the first place.

Considering most of the inner city’s roads now have a 30 km/h speed limit for cars, collision safety is probably even less of a concern now.

I do share the concern of others in the comments that such a system would probably be broken on day one, and you have a bunch of script kiddies with flipper zeros running around bricking ebikes.

The only way for that not to happen is to use proper encryption for any wireless signals being used to control this system. Considering the Dutch governmental reputation for IT failures, this is probably not going to go well.
