Nine in ten EV drivers won't switch back to petrol

Roughly nine in ten EV drivers wouldn't switch back to petrol or diesel, according to Indra's review of DfT and EVA England data, with EVA England's own survey putting the figure at 98% and Zapmap finding just 3% of fully electric drivers wanted out. That retention rate is worth noting for fleet business cases: driver pushback is the usual excuse for stalling EV rollout, and this evidence works against it. The same review cites Carbon Brief's estimate of £1,100-plus annual fuel savings versus petrol, assuming mostly home charging on a cheap tariff, which adds a cost argument to the retention data for fleets weighing up salary sacrifice and home charging infrastructure.
