it's actually a misconception that lane-splitting was always legal in california. it wasn't legal or illegal, rather it fell in this gray area where if you didn't ride in between cars like a jerkoff the cops would let you do it reasonably. the lane-splitting law was only officially passed in California this summer.
luckily for us since Cali has formally legalized it other states are taking the legislature to allow lane splitting more seriously. given time we will be able to filter and lane split throughout the US.
That's the dream. Hopefully everyone else catches on soon.
I think it is crazy to not allow it. As long as it is performed with consideration for other road users. So glad we can in the UK
It's really sad that it is not legal in Texas but I understand that the people here are not accustomed to such things and would either react aggressively or defensively, either of which could end disastrously.
