The "scooter or not" question could change quite a bit in the next few years.
At present I will not consider it, as I consider it far too dangerous.
But in the next few years, the number of scooters/motorbikes is expected to increase, and car driver awareness of these critters on the road will also increase. This might increase "bike safety", and I might just consider using such a 2-wheeler instead of my current 4-wheels.
If I have it correct, a 125cc "bike" is allowed on the highways, and by the time the super-train is operational, the N1 might be filled with scooters etc and there migt be no real need for the Gautrain.
It is impossible to tell what will happen. But I have my doubts if the Gautrain will do 100 000 passengers per day after a few years of operation.
My feel is that a secure, safe, clean, not overloaded rail system following the N1 between Pretoria and JHB with stations at every offramp would have been a much cheaper and better option. Maybe a longer ride, but it fits in with the current infrastructure and has more stations for growthpoints.
