Too many variables to say accurately, but I do know that most 3 and 4 cylinder engines make very little power at low RPM, where we normally drive them.
So, that said, it would be like accelerating from 1500 RPM in 4th gear constantly. (example) IOW, you leave the light normally, shift from first to 4th without accelerating past 1500RPM, then begin your acceleration.
For reference, give it a shot. Idle in fourth gear, record your speed, then accelerate to 30mph, timing your acceleration.
Once you've done that, drive normally to your 4th gear idle speed again, but in whatever gear you'd normally be in at this point (if you granny shift, 3rd on most cars) and accelerate to 30 the way you normally would. Time this acceleration as well.
This will give you a comparison between the two, and will give you INSIGHT (not a straight answer) as to whether you can drive stop and go easily with very low horsepower at 1:1 (helps to eliminate some variables).
