@AC (More of this, less of that?)
In addition to being the road-going equivalent of nerd glasses (you know, the black plastic ones, taped together at the bridge), there is the fact that the Peapod is incapable of even getting out of its own way. I don't know how things are in the UK, but for use here in the US, I would regard the stated top speed of 25mph as being inadequate even for use on non-highway roads. Needless to say, being incapable of being driven on the highways means that the Peapod would never be more than a niche vehicle anyway.
The Zeo, OTOH, should be capable of being used as a primary vehicle, provided the 250 mile range is something that can be achieved in anything like real-world use. A word of advice here. If you really care about weaning people away from the internal combustion engine, forget about the aversion to powerplants which which actually provide power in significant quantities.
Even if you think foregoing speed is desirable for its own sake, you are not going to convince the rest of us. What _can_ be done is to convince people to drive a "greener" car, provided they don't have to surrender any semblance of power and sex-appeal to do so. This is what cars like the Zeo can do.
Even if the Zeo styling is too over the top for some and it has insufficient room for others, it sends a message to drivers that they can do their part to save the ecosystem while still having a desirable ride. This message is much more likely to work than insisting that everyone don a hairshirt. After all, the ecosphere only responds to what we do or what we fail to do and is indifferent to how "virtuous" we are in the process.
