it comes as no surprise that the headline I just read was "plug-in hybrid Jeeps haven’t been able to engage the electric-only driving mode at all this winter."

 well, no shit. New tech isn't vetted and researched long enough to work out the bugs on the 1st year of a new vehicle production.... we've known that for decades

And batteries aren't made for shit and still don't work well in the deep freeze, that too, we've known for decades

I bet a regular Jeep with an internal combustion engine was unaffected by such bush league techy bullshit.
