I have a company provided vehicle and as such we must go through yearly driver-training refreshers online, then a drive-along every 3-5 years that is led by a co-worker. I'm one of my company's instructors.
I'm a Certified Smith System Driving Instructor. I'm not certain of how flexible they are regarding workload or travel, but I'll probably look into doing it for them when I retire in about 15 years.
The initial class to become an Instructor was 1 week, M-F 8-5. We met Monday at 8am, by 9am we were behind the wheel. We drove every day, in real traffic, all day till Friday at 5pm. It was most excellent and has changed how I exist behind the wheel in its entirety.
Here in the USA, we desperately need follow on driver training. Generally speaking, drivers are taught at 15-18 years old.
You know, when our attention spans are awesome, and we have great empathy for others.
Yet, everyone is an excellent driver. Just wait and read the responses after my post.
By the way, this is NOT for beginning drivers. This is Advanced Driver Techniques that demand above average abilties.
Look into it and see if it interests you.
