Range is fine too. 300-500 miles is plenty for a long distance truck doing 50-60 miles per hour. There are several manufacturers selling battery electrical class 8 trucks now. It will take a while for those to get common of course and for charging infrastructure to ramp up (these things need some serious amounts of juice). They have their required 45 minute break every few hours in any case. Great opportunity to charge the vehicle.
Range anxiety for commercial vehicles is not a thing. You might have personal anxiety but it's an entirely predictable thing that you can plan and budget for from a business point of view. It either is good/affordable enough and adequate or it is not.
In fact, it seems the low range delivery vans are popular because they are more cost effective and more efficient (less unneeded dead battery weight). Why spend the extra money on range you don't need? It seems the sweet spot is around 100 miles range. Some vans do even less than that. But it's more than the average delivery van does in a day apparently. Longer range options are available. Anxiety does not factor into this. It's a simple matter of "do we spend the 10-20k extra and is it worth it?"
except for that damn backup "beep beep". Yes, I know the arguments for safety, and few of them are based on studies which show safety improvements
esp vs other options, like backup cameras. Or if the beep only signaled if there was an obstruction behind the truck. That would be a great use for computer vision. Someone standing behind the truck (or even just something which might be a person)? Beep. Otherwise, keep quiet. An alarm which is false 10x more than it is true is not an alarm.
Despite that, there is an alternative which sounds more like a hiss. The main benefit is that you can identify the direction from your hearing. I have to look in all directions to find where the beep is coming from.
Smaller trucks move smaller quantities around the city from the warehouses.
Maybe sometimes you need to bring something especially large e.g. for a construction; such deliveries may be special-cased and planned carefully, instead of being completely off-limits.
