im a professional diesel mechanic for large trucks, and i have almost never heard of Nikola until now.
A little canadian company I am pretty excited about is Edison.
Instead of futuristic cabs and touchscreen everything, Edison is making trucks that professional over-the-road drivers have used for decades and know like the back of their hand. this is i believe what people on HN call "boring" technology but trust me, you do not want excitement on a 1400 mile drive. Theyre also targeting some of the most brutal applications for trucking including offroad logging and snow removal.
