From the screenshots you can see they've cleaned up the interface a bit, but they've not actually used any of this space - the menu still hangs below where buttons used to be.

This has room for improvement. Please copy what Google has done with Chrome and stop being academic.

"...the Prius is the most fuel efficient vehicle at each speed point from 1 mph to 100+ mph compared to any other car on the market."

I'd suggest this is untrue. A 1998 VW Passat TDI will do over 800 miles to a tank of diesel in the UK. Or cruising at 70mph on the motorway you can easily achieve 50-60 MPG. I appreciate that fuel in the UK is of a higher quality then in the USA, so the figures will be off. Also our gallons and of a different size. But still, these Priuses do not seem any more efficient, even here in the UK. I do not understand why they don't make a diesel/electric hybrid vehicle, surely that would be a perfect mix?

...it doesnt become a wild fire.
