It used to be every time we saw a Lexus on the road we'd make some joke about balding lawyers spending too much on a car that looked about the same as our 1992 Ford Tempo.

That was before we had the chance to drive a 2010 Lexus RX350 for a week. It only took a few miles behind the wheel to completely erase that old Tempo from our memory and adopt the Lexus as our new mistress of internal combustion.

Not because of the RX350's variable-valve timing, full-time active-torque-control all-wheel drive or the many other features we don't understand, but because all the gadgets, tech and luxury options on a fully loaded Lexus are like the Six Flags on Wheels we always dreamed of -- wheels with a lot more pick-up than that old Tempo.

Here's a few of our favorite features that have convinced us to throw out the Rogaine and apply to law school:

Heads Up Display
Despite what's happened to David Hasselhoff in the intervening years since "Knight Rider," we've all wanted to take a spin in KITT at some embarrassingly recent point in our lives. The Heads Up Display is about as close as we've come. An LED display projects your speed, audio selection and navigation information in bright white letters onto the windshield in front of the driver. While the RX350 might not take over the wheel so you can play arcade games on the display, it's a start.

Remote-Touch / Voice-Activated Controls
When it comes to controlling your environment while driving, the RX350 may have even outdone KITT. Navigation, the entertainment system and climate control can all be coordinated using voice commands (even with an obnoxious and inaccurate faux Scottish accent) or the remote-touch system, which is essentially a combination joystick and mouse located right next to the driver's lap. There's never any need to reach out or take your eyes off the road while shamefully enjoying Lady GaGa in private or trying to find the streets with the dirtiest names in a new town.

Ventilated Seats
We always wondered how those bald, chubby lawyer types still managed to look so cool in a Lexus. Turns out that ventilated seats make all the difference in the world, by keeping the driver and passenger dry and confident on hot, humid days rather than sweaty and leathery-smelling.

Adaptive Front-Lighting System
We could handle the fact that the RX350 is able to sense when the driver is approaching with the key fob and kindly turn on the lights and unlock the doors automatically, but we freaked out a little bit the first time our headlights shifted to the right to help us see around the turn we were about to make. If the RX350 can move its "eyes" on its own, what if it has to blink? Not the kind of thought to have if you've recently partaken of some K2. The system also automatically dims the high beams when it senses another car approaching (or your incredibly pasty friend Chris without his shirt on standing in the road).

Pre-Collision Warning System
Equally as freaky, but easier to appreciate, we never got to see this one in action. It uses radar technology to anticipate a potential collision; it then tightens the seat belts and primes the brakes for impact with your friend, Chris.

Monitors Everywhere
In addition to the main display in the dash and the Heads Up Display on the windshield, two optional backseat monitors can provide all forms of entertainment with the right setup, from satellite TV to DVDs or even Nintendo Wii. Just so the driver isn't totally left out of the game, there's the rear back-up camera that displays on the dash, and a wide-angle side-view monitor to check out blind spots, this display can be installed right on the rearview mirror to give you all the power of Big Brother in one central location.

6-Speed Automatic Transmission With Toggle
What this means is that the car is an automatic, but flip the shifter to the side and you can control what gear the car drives in without having to worry about a clutch. In other words, shift up and down with a flick of the wrist like a NASCAR driver, even though you have no idea what you're doing. And the best part is the car's on-board computer won't let you destroy the transmission -- if you're going too fast to drop it down into second, it's not going to let you do it -- but you can still pretend by making a louder revving noise with your mouth to be sure your friends are impressed.
