I put 1-5 yrs, but the more that I think about it, I probably should have been 6-10 yrs
Main reasons
1) I'm just not in the market for a new vehicle. My wrangler is 10 yrs old, but it's just a weekend toy at this point. I've got a company truck and I forsee that staying as a gas powered vehicle for quite a while.
2) Given that I move every couple of years, I'd be hesitant to by a full electric vehicle as there is a very good chance that I'll end up back in an apartment at some point and not having the ability charge at home/night really puts a damper on the practicality of a true EV.
3) The infrastructure isn't quite there yet. It's getting close, and in some areas it's far more practical than others (ie SoCal vs South Central IA)
4) That said, when I was living in LA for 6 months and truly commuting, I could see the advantages or benefit at least of a PHEV. That seems like the better transition for a lot of people.
