If you are interested in an informed opinion on EV vehicles. I'm a Canadian so I know all about long distances. I have a regular gas vehicle, a Plug-In Hybrid vehicle, and a full electric vehicle.
My EV is one of the very first models that came out, a Mitsubishi Imiev. It is ugly, old, terrible range (65km) and in the winter the cold weather means if I go on the Freeway the battery will run into issues and the turtle (reduced power mode) will come up. However, it is still an awesome vehicle for around the town trips. Its maintenance is basically zero (brake check every two years and top up brake fluid and wiper fluid annually). It is basically plug and play with nothing to really worry about.
As a second vehicle it is awesome. As an only vehicle it is useless. It just doesn't go far enough.
The plug in hybrid? My wife drives it back and forth to work daily in EV mode and charges at night. One tank of gas lasts roughly a month, sometimes longer. When needed for long road trips to our cabin (1300km away) or my mom's house (1400km) it performs admirably but the small gas tank mean regular fill ups. When I get to the cabin? It's generator mode mean I can power the cabin for up to a week and if I decide to go camping I can bring along a fridge and stove to cook at the camp :)
It can even tow but doesn't have huge towing capability.
The gas vehicle? Actually belongs to my son. Actually there are two (I have two sons). They are great and traditional but when they go into the shop for maintenance or repairs my kids steal my EV. When they are short on gas money, they steal my EV. For quick trips to the grocery store? They steal my EV.
I wish we had some of the Chinese EV's in Canada (a few are coming but not here yet). My Imiev really is aging poorly and needs to be replaced. With 300km range (even 200km real world) would mean I wouldn't need to switch out to the PHEV except for long road trips.
Side note: Renting a vehicle for those few times I actually do need to do a long road trip is surprisingly affordable. The money I save on gas and maintenance easily pay for those few times a year when I need the long range (and my wife doesn't want to give up the PHEV :)
