The EV tax credits were set to cost the government $A258 billion over a decade. The consensus amongst analysts is that the credits have been artificially sustaining growth in the EV market for these past years. Market analyst, iSeeCars, said that its data for various parts of the US shows that EV penetration slows when EV share reaches seven per cent or eight per cent; and that has occurred with the subsidy. However, some industry groups disagree, arguing that the EV FBT exemption is successful in driving EV adoption and is needed in combination with the NVES to meet emissions. “iSeeCars has been tracking EV market share in cities and states for several years, and the data consistently showed between 7 per cent and 8 per cent as the tipping point where growth in EV share slowed dramatically.
