The purchasing process is the barrier to entry. Municipalities are required to run a request for proposal on anything over ~10k. The RFP gets awarded to a PE owned manufacturer that then takes 4+ years to deliver. The municipality is locked into the vehicles they don't have so a new market entry needs to simultaneously establish a track record that qualifies them for being awarded an RFP and be able to wait out the purchase lag. Not impossible, but easier said than done.
