Scenario for post 2035 (when manufacture of ICE powered cars becomes illegal in UK, Europe and other supposedly 'developed' countries)
1. Continued manufacture of ICE powered vehicles by 'renegade' non-compliant and third world countries with existing car plants 'feeding' continual demand for ICE powered vehicles.
2. Annual consumption of Petrol and Derv starts to reduce. Oil supplying countries, fuel refineries, distributors, wholesalers and retailers will be forced to increase wholesale and pump prices in order to cover for the reduced volumes of fuel sold at the pumps.
3. Year-on-year as conventional older ICE powered vehicles are forced to be scrapped (due to unavailabilty of parts and difficulties in continuing to meet emission standards) volumes of ICE fuel consumed will reduce in successive years further increasing costs at the pumps (for the reasons in 2. above).
4. Our own HMG will look to further increase fuel tax as nett tax and Vat revenues significantly reduce (due to the reasons in 1. and 2. above)
5. Synthetic fuels whilst having limited availabilty currently never actually materialise as cost effective alternatives to petrol and derv as HMG refuse to consider reduction of taxation levels (to make synthetic on par with conventional fossil fuels). Even further fuel increases due to ever increasing downturn in petrol and Derv usage as per 2. and 3. above)
6. Classic car ownership becomes an increasingly expensive 'luxury' due to costs of fuel but oddly a logical alternative (to those who will be able to afford to use them) to any remaining ICE powered cars manufactured between the 1980's and 2035. This will be due to unavailability of electronic componentry and non-servicability of suitable diagnostic equipment.
7. At various points during the decade following 2035 the UK's unmaintained road network will multiple suffer massive gridlock scenarios where thousands of stranded electric vehicles will be 'marooned' possibly for days at a time while waiting for recovery services.
