Yep. 2.5s is the average perception reaction time. This includes

Perceiving the person
Understanding the situation and thinking about whether you need to stop
Moving your foot to the brake pedal

Keep in mind, most people feel comfortable driving and not expecting to have to make an emergency stop at all times. Sure, you'd be ninja-fast if you were in some test environment where you expected the hazard and were trigger happy on the brake but that's not the real world.

A few US states, including California, have adopted a standard driver reaction time of 2.5 seconds. The United Kingdom's Highway Code and the Association of Chief Police Officers ACPO Code of Practice for Operational Use of Road Policing Enforcement Technology use 3.0 seconds for driver reaction time.
