Relatively small increases in speed dramatically increase the stopping distance and as such the danger of driving. Especially with a huge truck like that. That's why Amsterdam (with much more food traffic) has recently reduced speed limits a lot.
> At 30km/h, the stopping distance of a car is 13 metres. At 50km/h it’s more than double at 27 metres. That 20km/h reduction is the crucial difference between a pedestrian or cyclist surviving the impact of an accident – at 30km/h it’s estimated that 95 per cent of pedestrians would emerge relatively unscathed.

What you're saying is all true, but typically road design influence driving speed more than anything. Changing speed limits rarely has an impact on that (at least in the US).
