Auto execs and engineers taking a pauseThe complete saying is "don't count your chickens before they hatch", but there are many, many eggs that are going to be produced. In the early days, Exro spoke of a "target-rich market" to be satisfied. Though EV development has slowed somewhat, I think that's due to a number of factors, all of which will be change in a hurry.
There are advances being made in technology such as cheaper electric motors (no rare earth minerals required), an increased supply of Lithium and other minerals, research on the development of less expensive batteries, and of course other things like Exro's coil driver and better vehicle platform designs (think SEA Electric). Also Tesla is working on a much less expensive compact EV, which at $25000 USD is intended to be affordable for "everyone".
All of that would prompt auto execs and engineers to take a pause to do their homework before expending the billions necessary to develop future EVs. So I am not troubled by EVs not penetrating the market as fast as originally expected. It also gives Exro more time to grow and position themselves for the eventual and inevitable breakout. Time is required but It's all good looking ahead!
