There you go, I've got no problem at all with that as long as you understand that you come in to MY lane if I allow it
Here's a tip too, just passively indicate is your best bet. Just trying to push in whilst indicating just ain't going to work I'm afraid even if you are an "advanced" driver.
Unfortunately the passive indication isn't going to help if you drive a BMW or a taxi I'm afraid but then you wouldn't be doing that if you drove either would you!
