Depending on the environment, the Lexus LS 460L can be fun to drive. Like when accelerating in a straight line. Or when pulling up to a high school class reunion. What robs the car of its ability to entertain its driver is the electronic brake-by-wire system necessary for the LS 460’s various safety technologies to work as advertised. We’ve complained about brake pedal feel and modulation in the IS 350 and GS 430 – here, the complaint remains. The braking system works brilliantly the few times you’re engaged in a real panic stop. The rest of the time it’s a complete deal breaker.
