So my general observations, for example, on roads:
the lack of speed limits on many highways, or only two lanes on others, which leads to many more lane-changing manouevres between high- and low-speed lanes; or very short-throw entry and exit lanes with extremely sharp curves and abrupt changes of speed; lack of organization and coordination around road-works to provide safe alternatives; the multitude of badly-designed junctions; terrible signage blocking traffic lights and visibility of oncoming traffic; the lack of ice and snow clearance on roads and pavements and cycle lanes; And I say this as someone who rides my bicycle every weekday to get to class. It's been a nightmare and I've just fitted studded tyres which has massively helped. In the UK, these routes would have been cleared.
I mean, both countries are pretty safe on the global scale of things, so we're complaining about things of a high standard to start with, but the figures kind of bear this out:

And the UK (or Great Britain which is just the mainland) had 706 car user deaths in 2021 compared with 1118 in Germany which is quite considerable. Injuries are harder to compare because of the variation in severity and the scale by which they are measured, but a dead body is a dead body. Fatalities means deaths occurring within 30 days of an RTA.
So when you get to Road Deaths, as opposed to car users, Germany jumps to 2562 deaths in 2021 vs 1608 for the UK, and that is 31/million pop vs 24/million pop to normalize things (no normalized figures on the sheet for car users).
