Actual physics aside, you will NEVER get similar energy consumption between EV and ICE vehicles, no matter how fast you travel. EVs always use less energy to do the same work as an ICEV because the ICEV wastes much more energy as useless heat per each cylinder firing, and that is why it always needs extreme cooling. If not, that excess heat will damage the engine. A turbo-charger can recover and reuse some of that excess energy from the exhaust, but not as much as one may guess. Even if you were coasting or rolling downhill, that gas engine is still burning fuel and just dumping that energy out to the atmosphere.
Consider how much energy the Bolt EV battery has when fully charged (average of 57 kWh). Then convert that to the equal energy level of gasoline. You will be surprised that the Bolt EV carries less the the equivalent energy of three gallons of gasoline!
Very well put. Some will still spin this to show that even with the biggest batteries that are practical for a car, you can only get the equivalent of 3 gallons of gas, as if that's a negative. You've pointed out the fallacy of that position with the increase in efficiency that trumps any counterpoint.
To the OP, even if you take the range issue away, the driving experience is so much better with the EV that it's hard to describe to someone that's not experience it.
I'll give a few examples that recently happened to me. Took my first road trip this past weekend of about 750 miles in a long range EV. My main squeeze was skeptical of the entire EV experience even though I've been driving a Leaf for 3 years and she's always liked it for what it was. She just doesn't handle adversity well and any deviation from the "plan" can be traumatic for her. Needless to say, the smooth acceleration, quiet ride, handling, zero compromises, has her at least thinking that maybe an EV is in her future.
When we got back home, she got back in her Suburu and called 30 minutes later to say just how antiquated and terrible it felt compared to the EV. Unless you've had a chance to really spend some time in one, it's hard to convince the other side how much better they really are.
The other example is her brothers. She has 4 of which all are involved in mechanics of some sort to varying degrees. 2 are engineers and the other 2 are mechanics, one has his own repair shop and the other is a seasoned pilot that does heavy equipment repair. 3 took the car for a ride and all were blown away at how much better in every way the EV is to a comparable ICEV. The brother that is the car mechanic was very enthusiastic about their future and lamented about how much money is spent currently just dealing with all the emission crap.
I've found that generally, anyone that has a negative POV about anything related to any EV, has not actually experience it. They have a preconceived notion based on here say and rumors and are convinced it's not going to work for them. Again, this is excluding the range issue which valid for every EV except one.
