I agree as well. Flat pricing/Tesla (and Saturn from long ago) is a more efficient model. As dealers make most of their money in service now, I think they would actually do better in the long run as well moving to a fixed price model (via fewer sales people). The haggle method only works well for non-standard goods with limited supply and difficult value propositions (like antiques).
My sadness is that Dealers have largely missed their opportunity to become the electric gas stations of the future, moving away from heavy sales teams to service and concessions/retail while the customers charge up. As they are good (but not perfectly) distributed across the country, it could have made an overnight supercharger equivalent.
None of the old line manufacturers could see their way through how Tesla has changed the business model. Sadly now I think its almost too late.
EA, EVgo, and maybe Chargepoint will take over (in the US) for BP, Shell, etc.. but in a more limited capacity than the historic stations. Most with home charging only get 10-20% of their juice off of public chargers. Often less. So we only need a quarter of the stalls that were needed in the fossil fuel era.
