If conditions exist I accelerate at almost the slowest rate possible.

For instance on a flat road from 0-35 I'll "surf" the edge to just barely keep the Assist on. (Without Assist the acceleration rate is zero)
Between 35-40 I'll raise it to about 60MPH and accelerate from there.
Once I get to around 45 I can raise it higher between 70-80MPG.

0-45MPH in about 40 seconds.
But that's only if I'm solo. If I have passengers I'll gas it a little more.

Efficient drivers do it better.
