Electric cars (even more than Hybrids) take benefit mostly by drinving in urban environments, rather than on highways, compared to (purely) combustion engine driven cars. That is where the limited range and charging/battery life issues dont play that much of a role as well.
This is due to recuperation, aka. converting kinetic energy back into electric energy in the batteries, instead of just uselessly heating up brake disks.
On highways however (aka. constant speed scenario) it doesnt matter much. If you drive (alone!) a 1t Vehicle, powered by combustion, hybrid, electric, or hydrogen, you are wasting lots of energy. The efficiency of the given propulsion (ok, and availiability of fuel) based on releasing chemical energy will only change this within given limits. Only with stuff like thermonuclear fusion which is insanely more fuel efficient, and where fuel can be availiable in abundance (hydrogen is the most common element in the universe and can be gained by fissioning the most abundant stuff on the surface of the earth, water) this can be changed funamentally.
You may however work on the carbon footprint, by chosing a propulsion which is most advantageous, but still....you are wasting heaps of energy moving your 150lb body and some baggage around with 1-t vehicles.
Individual traffic as we know is the problem in itself, which should be replaced with something less wasteful, in the long run. Live long and prosper!
