True on the Prodigy applying brakes when the brake lights illuminate, mine does that too. But if you think about it, Most people need to take their foot off the accelerator to do a light pres on the brake pedal. Sure some can left foot the pedal. But when caught unaware I'm betting that muscle memory will act faster for most people. At that point people might be more prone to pressing hard on the pedal like in a panic stop. So which would be worse in a sway situation, pressing too hard on the brake pedal, or too hard on the trailer brake lever?
As far as the lever, you bring up a good point. The lever is proportional and brakes harder the more you push it. The idea is probably not to slam the lever fully over to engage the trailer brakes. But rather to apply the lever at some point that applies the brakes, but doesn't just immediately lock up the wheels. Each situation is going to be different. But once you have your hand on the lever, or the pedal you may be able to modulate the brakes better from that point. So maybe the drill should include only applying the brake lever 1/4 to 1/2 press. The idea here being to practice not panicking and instead applying the lever in a controlled manner.
