At present the purchase price is the market killer for EVs & once the price comes down to that of an equivalent ICE, IMO they will achieve significant market penetration.
Toyota's hybrids had a very slow start because they were expensive and they were only were suitable for Taxis that put up 100Ks P/A. As the price gap between them and ICEs dropped, market share increased.
IMO the best way for Aus o rapidly decrease vehicle CO2 emissions and the import fuel bill is to allow the importation of cheap used Japanese cars to replace the fuel guzzlers owned by those who can't afford to spend over $5K for a car. This would also drop the pricing of used cars in Aus generally and put downward pressure on new car pricing, IMO.
In 2002 the then local manufacturers mad submissions to a senate inquiry that to continue the then Used Car Import Scheme would put new car manufacturing in jeopardy because of downward price pressure.
If that was true then according to the manufacturers, then why is it not true now?
