One thing I can do, though, with an ICE vehicle (granted - only safely with trucks and similar) is carry a can (or more) of fuel with me, and the extra weight of that fuel is minimal in comparison. Meaning I can travel much further or refill in an emergency as needed, if I don't have any way of getting fuel otherwise. I can't see how this would ever be possible with a battery; you can't carry around a partial battery (well, you could - in theory - but install it?), and full-sized battery is going to be difficult to carry around (and possibly impossible to install). This is important for certain vehicle types - namely off-road vehicles. Such vehicles tend to consume more fuel (for various reasons), and off-road you may be far from people, let alone a gas station. Plus you may want to do a longer trail (or need to for some reason - maybe a detour forces you off your original route to a longer one) while still being able to get back to civilization at the end. Being able to stop and refuel on the trail is important. Until battery tech gets to the point where that's no longer the problem, I can't see off-road vehicles being anything but ICE. Perhaps if they could double or more the range of current batteries, that would probably do it - I say that much because off-road vehicles, due to weight, size, and such already drop current batteries to the point where you're lucky to go 75 miles on a charge off-road; though that's only known with some custom conversions - a purpose built off-road electric vehicle might be different. Which I honestly hope happens - there are a ton of advantages to be gained off-roading by electrics; the instant all-wheel traction control alone would be a game changer - not to mention the sheer torque and torque availability.
