Politico meddling that backfires.
Two good examples:
1. a)”We’d like you to use less fuel, so everyone should drive diesels”.
Five years later, having noticed a hole in the tax revenue from fuel
b)”We’ve realized that diesels are worse polluters than ANYTHING, (they aren’t), so we’re increasing the duty on it and want you to stop driving diesels”.
2.a)”In order to cut down use of electricity we want everyone stop using incandescent light bulbs, and switch to pinkish coloured cold fluorescents which can take an age to reach colour temperature”.
b)”Now we want you all to dump your CFL bulbs and switch to ten times as expensive to buy LED. The upside is that an LED bulb lasts up to 50,000 hours!
(The LEDs might, but most of the drivers struggle to get past 500 hours).
