St Georges Road, OBESRVATORY: JRA SAFETY UPGRADE APPROVAL

I wish to insist that the measures taken (specifically hump or bump in the road) NOT be unreasonable in so far as they pose a risk of damage to vehicles that drive over them at a safe legal speed. Too many bumps in the roads in JHB are just too excessively high or steep that a regular road-worthy and not over-loaded vehicle gets scraped and damaged by traveling over them.
Also ideally any measures should only enforce the legal limit of 60 km/h and not reduce the safe and comfortable speed limit of this (or any regular road for that matter) to less than 50 or 40 km/h (unless in extra-ordinary circumstances a greatly reduced speed is imperative for e.g. a hair-pin bend or notoriously dangerous accident/collision prone corner etc. [otherwise basically the speed of all JHB roads is slowly going to be 20km/h !!!])
