This is fantastic news. At last some positive action against dangerous speeders.
Cars will be fitted with GPS or camera technology and will not be capable of exceeding the posted limit.
The limitation can be temporarily overriden to get a burst of power if the driver needs to take evasive action of safely complete an overtaking manoeuvre.
This is long overdue. Road deaths will plummet. Speed will be reduced.
Hopefully this means poxy speed ramps will be abolished now.
