Fewer off the shelf parts to slap together on an ev. The best investment strategy is to diversify limited investment dollars.There is even an article that briefly also talks about Elio: http://gas2.org/2016/10/07/sondors-electric-car-everything-elio-not/
If it goes anything like the eBike, it will get built using 100% Chinese parts and labor, hit the pricepoint but then tack on heavy shipping/delivery fees, and have very little in the way of actual engineering. But it will get built.
I was in the process of building my ebike when they first started taking orders for his original bike, back when it was called the "Storm", I think? They initially made BIG claims regarding mileage that they eventually reined in to realistic range for their small battery. What they ended up making and delivering was a cheap but decent quality no-frills ebike with off-the-shelf parts at a pretty small profit margin, but sold A LOT of them. Last I heard it was 15,000. Sound familiar? They sold for $500, but had a steep $200 delivery fee. It was still a bargain at $700 if you were in the market for an electric assist 20 MPH ebike.
I was building essentially a 40-50 MPH electric motorcycle on a bike frame so was not the target audience, but I understand the appeal. Mine only cost around $800 to be faster with more range and better gear, but also spent many weekends on the build and no warranty.
What I love about Elio is that they are trying really hard to engineer a good vehicle. Not just slap together some parts under pretty bodywork and call it a day. There is a difference between working and working well, and from what I have seen Elio is trying to work well. Sondors may surprise, and I hope he does, but for now I am going to keep putting my excess investment money into Elio.
