I can answer one of those questions. The EA is safer in terms of its drivers, rather than the car itself. They are fairly slow in 3 speed form, and are not hugely popular with enthusiasts.
The other day, I saw some guy hooning around in an AU III in the wet. ABS/airbags or not, you'd be much safer in a sensibly-driven EA.
