Three-wheelin' on liaison has been banned for a decade.
I think it was banned 2-3 years ago at most.

What Meeke did in Portugal was change in a tyre with only a wheel, no rubber, to save the deflating tyre to go through the liaison to service. This kind of trickery won't be allowed anymore.
And that's a good thing, why?

Show me a rally which has taken advantage of the 500 km limit and not just going near the minimum 300 km? Although, Monte, Mexico and some others have been between 350 to 400 km in the latest years, but it won't be much of a shortening for them still. And Monte does not have to obey any rules anyway
So again, why did they feel the need to pass a new regulation to make it impossible to have more than 350 km?

I know why. It's because they wanted to have a justification for when they bring back "Safari" and it's only 300 km long. "Oh yeah, we wanted to make it really long like the old safari, but these rules that we just passed forbid it, so it's going to have to be 300km going in circles on private land. Sooooooorry. "
