A good example would be the wind being pushed by a semi or a wind blowing down a canyon that crosses to road. I like it to be my decision when to change lanes. Mechanical brakes are not designed for 75 MPH. The steering and suspension are not designed for 75 MPH.

Agreed 100%!! I never drive my A at 75 mph for every reason and then some as you stated. I avoid the freeway 95% of the time, here in Southern California, mostly due to idiot drivers.

The takeaway, for me, on the T5 conversion was the syncros that allowed easier shifting around town and the closer ratio of gears between first and fourth. Around town, with the stock box, second seemed to get rung out a little farther than I preferred and third tended to be a little too tall. Splitting the difference with the T5's gearing seemed to helped a lot. Food for thought I guess...
