The Vehicle Unit of Monash University have actually investigated this and found that there is no difference of accident rates caused by mechanical failures between jurisdictions that have annual roadworthys and those that don't.
The reasons were complex but the main reason was that in the states with roadworthies drivers tend not to maintain their cars as well and let the tester pick up things once a year and if things like tyres are noticed before hand they are left until testing time and do it then. In states with no roadworthys owners tend to fix things when they pick them up - now these are overall findings and we all know people who do nothing and others who do a lot.
