You may as well say the same about motorcycles. And yet plenty of us ride and enjoy motorcycles.
I'm always cognizant of my lack of stopping power when on my motorcycle and so leave a wide berth between myself and any vehicle ahead of me. I suppose someone not used to that mindset finding themselves in a 3-wheeler might be forgiven for thinking they were in a car.
Nowadays, driving a vehicle without these technologies seems crazy. But those machines are not for everyday use: they are a special kind of entertainment for passionate people, those who most likely know what they are doing.
It still happens to be surprised by a situation, like the one top post seems to describe, and even with great experience it can become tricky to stop, with or without technology.
