Thank you for helping bring this aspect to light, I've found an old article that goes into some detail below.

The velomobile: neither bicycle nor car

Fully enclosed velomobiles give the best protection against bad weather, of course, but they do carry a few disadvantages. The main problem has to do with ventilation. Even in cold weather, the driver may “overheat”. A body that delivers 200 watts, produces around 1000 watts of waste heat, which mostly escapes via the head. In a fully enclosed velomobile hearing and sight are also affected. The windshield can steam up or it can become opaque because of rain or snow (windscreen wipers are not an option on any velomobile, probably because of the extra weight that would be added by motor and battery).

A fully enclosed velomobile thus needs an efficient natural ventilation system (which can happen via air intake in the nose of the vehicle). Some manufacturers have come up with a compromise...........

If all 300 million Americans replace their car with an electric velomobile, they need only 25 % of the electricity produced by existing American wind turbines
