Hybrid Failure #1: Initial Acceleration

So one of the failures of the p-hybrid in my opinion deals with Initial Acceleration.

Acceleration, the change of velocity over time.

But with our former 07' p-hybrid, low to no initial velocity over time can equal to a non-responsive motion.

Example 1.

You are waiting to make a left hand turn on a two lane road. Traffic is constant, but after waiting for several minutes, you decide you have enough time to hammer on the gas to turn left before another vehicle comes barreling down the road. Ah, here is the problem, when you hit the gas pedal the car moves forward slowly, as if the engine stalls, then the engine get's the clue that you have hit the pedal the car rev's up and then goes. But the critical part of the problem is the time period between the initial gas pedal initiation for about a couple of seconds. This problem on the 2007 p-hybrid was one of the reasons why it was traded in.

What they did to fix the problem on new models?

The designers have created a "power mode". The Power mode has a greater gas-pedal sensitivity for enhanced acceleration. This is great news, but was this not thought about when you sold the first and second generation vehicles? You would believe that acceleration would be the main component of designing a vehicle. Not to bag on the car company, but this was a serious non-recall issue I found that was not-acceptable.
