Ten-ish years ago I worked on a trading system. NASDAQ created a new regulation that required us to change how our system worked on a very tight deadline. As an eager eng manager I was ready to pause other projects and dive into it.
My business folks said there was no way this regulation would go into effect on time. They bet none of our competitors would comply in time and the exchange would have to extend the timeline by many months.
This also applies to start up difficulties in software/service ecosystems, where everyone is waiting for the greater fool to jump in and pay the "first through the door" cost. The GM EV1 is a great example of this.

So we did nothing, and they were right.
