It’s not really ideal to have no front end from an aerodynamics perspective so I don’t think this is true from a universal perspective, although obviously some vehicles will want to prioritize space/footprint over aerodynamics, but many won’t.
A relatively blunt nose isn’t inherently disadvantageous from an aerodynamic perspective. In fact, it can often lead to better overall airflow relative to a tapered nose on a traditional car.
Can’t be that big of a draw back to not have a nose, eggs are pretty aerodynamic no? Regardless I’m sure well reach a point where range doesn’t matter anymore, I would argue it already doesn’t but everyone thinks they need 300+miles to be able to get to work every day lol.
The best shape for aero is teardrop or egg shaped with the round part in front and the tapered part in the rear, so there’s no reason why losing the hood is a bad thing for efficiency.
The height is a big issue for efficiency here - low cars obviously get much better efficiency from the same shape - but the shape itself, especially at the front, looks pretty efficient.
You know what would be badass? HD inflated nose cone and rear end. Inflated when traveling on open roads and improves drag coefficient. Not sure if this is practical but semis do have a metal oragami thing that is at the back of the trailer.

Yeah someone posted an aerodynamics analysis awhile ago, and basically the conclusion was reverse teardrop design provides best airflow

they use fluid dynamics these days, the wind tunnel is a computer.
Canoo:
BODY
• Steel body
• Drag coefficient: CdA 1.04 (Cd 0.33)
• Cabin mounted on rolling chassis (skateboard architecture)
• Thermoplastic (thermoplastic polymer) outer skin is robust, lightweight, corrosion free and dent resistant
.33 is towards the bottom, but not bad (F150 is .5, Volvos come in around .3)

Delivery trucks don’t necessarily need to be aerodynamic. If their use case is in town or a lot of stop and go.
