I shift into fifth gear and hit 70 mph as I merge onto the State Highway 130 toll road east of Austin. The speed limit on this road is 80 mph, so that's where I stop accelerating until a Chevy Tahoe packed with children passes me in the left lane, probably doing around 90. Then I decide to push the accelerator a bit more and let my speedometer creep up to 85.
At this moment, I am breaking Texas law. That won't be the case in November, when a new section of SH 130 opens up with an 85 mph speed limit — the fastest in the Western Hemisphere, according to some reports.
