"There are plans in progress at the moment to have a 500 truck rental fleet in North America by the end of 2023."

From my vantage point, pretty ambitious goals for an unknown, unproven supplier promoting unproven product(s) (i.e. not field proven), that has zero authorized distributors and/or trained service technicians (aka engineers), local parts supply (or module supply) and other product support capabilities like operator training,, within North America.
BTW where would these 500 units be built???
