Research 1 to 300 km/h
Summary

It may be difficult for TRL to admit to their 1,000 Clients in 145 countries worldwide that they made the mistake 73 years on stopping distances which has led to carnage on the roads.  It is this mistake on stopping distances which has resulted in others setting incorrect speed limits and incorrectly timing amber traffic lights.

When 50 km/h is correct on a one-way road then 35 km/h is correct on a similar two-way road.

When 100 km/h is correct on a one-way road then 70 km/h is correct on a similar two-way road.

When 120 km/h is correct on a one-way road then 85 km/h is correct on a similar two-way road.

Driving Tests at 20 km/h on roads with ramps and ‘N Plates’ are mistakes,

The control of a speed of 1 to 300 km/h is outlined to prove my discovery.

TRL, Highway Code, RSA, DVSA, Police and others declined an invitation to disprove my findings.

Are fatalities set to continue or will my discovery be accepted after 22 years of correspondence?

The aim of my research is to eliminate road crashes worldwide.
