Ironically, “running the country like a business”.
Have policy outline an objective, Set KPIs, thresholds, etc. If the policy fails to meet them it gets automatically canned. Otherwise it’s safe.
Want to lower road deaths, that is your policy “lower road deaths by 2030 by 10%”. (Largely) A goal everyone can get behind.
But you’ve got to specify how you measure it, allow all parties to add their own metrics like “average journey time must not increase by 5%” or “maintain 99% licensing in rural communities”.
How you achieve the policy is (mostly) irrelevant. Want to do it by lowering speed? Fine. But that might increase journey time significantly. You could improve driver training, but that might impact rural communities.
Subsequent governments could cancel it, but only if it’s failing its KPIs, or if their new policy is “don’t lower road deaths” or “make cars go faster”
VW can’t use the factories they have.
