It has more to do with the transmission. Most EVs are more aerodynamic than ICEVs but still suffer at high speeds because they lack a transmission and thus require more power to maintain high engine RPMs. An ICE in comparison has a transmission to reduce the RPMs at high speeds.

That's fine but not everyone needs that range. On a daily basis most people do not travel more than 100 miles. Even the slowest L1 charger can put 60 miles of range on an EV overnight plugged into a regular outlet. An L2 charger using a 30a outlet, found in most laundry rooms, can do ~20 miles an hour.
Every two car family where one person has a commute of less than 100 miles round trip would be just fine with an EV equivalent to a Nissan Leaf.
Still a distinction without a difference.

Of course not, I quite specifically mentioned that it was my specific requirement in the original comment.

Good for you. A leaf still is of little use to me. Even if the infrastructure were in place, which it is not.
That means they don't perform period, ICE don't magically avoid aerodynamic drag.
> A 600 mile range use-case is a boundary condition at best as there are few ICE vehicles that can even achieve that.
Every ICE I've driven was able to achieve around that level. A 200~300mi range is what's ridiculous(ly low). The best car I've had could exceed 850 at 60~65mph.
