No collaboration means less opportunities for learning from people (even the post admits!) that are "better at what you are doing than you are", which imo stunts personal growth.
Decision makers need to be clearly appointed, accountable, and empowered to follow through. But that power then also comes with listening to feedback from all relevant parties. As long as they trust that they're being listened to, they don't get a say in the actual decision making process themselves. I also agree about taking reversible decisions faster.
Another point I deeply disagree with is
> collaboration forces the driver to slow down and explain stuff (background, context, their thinking).
Yeah, and that's a good thing. It forces them to properly think through their thoughts, if they can't explain what they want to do clearly and why, it probably shouldn't be done. Quality goes up by slowing down.
