Actually the Ford Escape (and for that matter the current Fusion/C-Max) were/are in the "Strong parallel hybrid" category and the Honda system was a weak parallel per your definitions.
The West Coast EV highway project has dealt with some of that, putting 50kW charging stations (CHAdeMO for the moment) every 25 miles or so along the I-5 corridor and other select routes in the Northwest US. Most of the charging locations are at restaurants or other businesses that provide services commensurate with the half hour or so one might spend waiting for a charge.
Based on personal experience that's not the case. After 2.5 years and 41K miles my effective range is essentially unchanged from when the car was new. Part of it is how I maintain charge (I tend to charge to 80 percent unless I know I will be needing more).
In fact, the battery is considered to be at the end of its "useful life" when it's down to 60-75 percent of original capacity. At that point it's expected to still have considerable value in stationary applications where absolute capacity is less of an issue.
It's already been done. AAA has such rescue vehicles in select markets...they put a battery or a good-sized generator on board that can give you enough of a boost to get to the next charging station.
The capabilities sound very similar to the dual-sensor setup in the HTC One M8, right down to the 4MP resolution.
HTC managed to get that in a $650 smartphone...
I have only one thing to say to those who think the FCC regulates too much:
AM Stereo
The FCC took a hands-off approach to AM Stereo and we ended up with a colossal mess.
Sorry folks, there are times when government regulation is the only way to enable the world to work.
