I don’t think it’s a good idea. The car chase sequence is one of the few scenes where we can see Obi-Wan and Anakin acting like friends, it is a scene where we can see them teasing each other in a friendly way, instead of always having a rocky relationship. Unlike many people on the forum, I generally don’t have a problem with them having a rocky relationship, but removing one of the scenes where they act friendly towards each other is not a good idea. After all, you need a reminder that they are still friends, even though they have a rocky relationship sometimes. So, I personally don’t like the idea. Removing that scene could improve the pacing, but would not improve Anakin and Obi-Wan’s friendship. And the training dual from Kenobi is not enough to show their friendship, in my opinion.
