Motorists could be stuck in congestion nearly twice as bad as current levels if self-driving cars become commonplace, a Government report warns.
Department for Transport (DfT) traffic projections for England and Wales show delays may rise by up to 85% from 2025 to 2060 in that scenario.
The analysis is based on connected and autonomous vehicles making up half of the car fleet by 2047, and a “fast uptake” of electric vehicles.
This would lead to more traffic by “increasing the mobility of the elderly and those who do not currently hold a driving licence”, according to the report.
