It sounds very similar. In the past we had the 20-years-regulations, too, but this was cancelled by the insurance-companies. Reason: there were coming too many cars like Mercedes 190, VW Golf II, Scirocco II, Opel Kadett E, which were old enough, but reliable enough still today, so used -illegally- as all-day cars. And often by younger people, who make more crashes. When the "Schadenquote" got up to 500% (means: for 1 Euro fee, the insurance had to give out 5 Euro for claims and damages), they stopped the 20-year-regulation and have made the 30-years-rule.
