I would like to see much better testing of license applicants... This could be done with driving simulators, which is the only safe way that a kid suddenly appears in front of you, and the only way skidding on a wet road can be simulated safely. All candidates could get a score out of 100 say, and this would be objective.
The only downside I can think of would be that a different car to your normal one would be used in the simulator.
Kids would do well in the scores but would still drive stupidly on the real road, but oldies who reacted too slowly to be safe would be caught out.
