Things to consider

How much can change in 20 seconds.

In a real world situation could you clearly see ahead 270 metres.

270 metres is about the same as 40 houses… many houses are in your street?… long is your street?

On our high streets cyclists travel between 15 & 25mph, and yet we see vehicles overtaking with ease….what speed must these vehicles be travelling in order to achieve this?
