Take Two's car critic Susan Carpenter is just back from Las Vegas, where she was at the SEMA show. It's a trade exhibition for car customizers and specialty parts companies. SEMA is all about tricking out cars, and Carpenter tells Take Two there were some radical ones, including a 1958 Jeep, perfectly restored and sporting tank-like tracks rather than tires.

Carpenter also gives her review of a new motorcycle documentary. It's an update of the classic Bruce Brown film, "On Any Sunday." Brown is perhaps best known for his surfing film, "Endless Summer." Now his son has taken his father's template, and made a motorcycle documentary for the 21st Century.

Finally, it's getting darker earlier, and that spells danger for bicyclists. Carpenter points out most bikes aren't sold with head and tail lights. And that's a problem because safety studies show an increase in cyclist fatalities after dark. An LA-area firm has come to the rescue with a couple of interesting innovations. One is a bike that glows in the dark. The company also sells bikes that use LEDs to illuminate the bike from the front, back and sides. Carpenter says not only does it make the bike stand out to nearby vehicles, it also increases the rider's visibility on poorly lit streets.

Susan Carpenter is auto and motorcycle critic for the OC Register. She joins Take Two on Thursdays for The Wheel Thing.
