We absolutely have the ability to measure acceleration very accurately. It's a necessary part of having an inertial navigation system.
You could even do what autobrake does: set a target acceleration, and adjust thrust (instead of brakes) to maintain that desired acceleration.
There's a decent number of accidents that have been caused by incorrect thrust or weight settings/calculations; MK1602 is the poster child. A proper accurate acceleration check would pick those up, too.
