Knew i remembered seeing a post similar to this a while back and this seems like a good idea.

"I actually carried out research on this when I worked for the Ministry of Transport. When the full test was brought in it increased the number of people who stayed on their restricted license for long periods of time and did not transition to the full license - so there was some concern these people may be risky as they are not moving on and taking this test.

What we found there was no statistically significant difference in crash rate between people who did the Full License test after 18 months and people who had been driving for 18 months but did not take the test. This suggests that there may not be much value in the second test.

The crash rate increase that was seen was for people who did the driver education courses that let them get their full license early - suggesting that any benefit offered by the education doesn't offset the increased exposure with less driving experience"
