Yes unfortunately I had to let my foot off (just had a look at it and I gave it the wrong caption :p) , when there's a lag, it's due to me chickening out or a car coming in the fast lane.
These were not good videos, I shall make better ones tomorrow or the day after on the ring road with full flooring.
I think the auto has a better handling than the manual - maybe it's because I don't drive the manual like a normal person.
And it doesn't feel underpowered at all-atleast till a speed of 100 km/hr. I drove a belta ( the current model we see everyday) in islamabad and it felt extremely laggy in the speeds of 60-80 km/hr and kinda unstable.
And yes, I understand by what you mean by taking the foot off and then flooring it... I have this problem while driving the '13 Civic prosmatec on slopes on the motorway between kalar kahar and islamabad.
