"The industry needs to take a reality check, it's driven by profit and sales and the technical side has fallen behind whereas the software/hardware of the vehicle is moving forward in great technical strides"
This is very true, but not the whole story.

I got into the vehicle repair trade by taking the path of least resistance in joining the family business. Something I've lived to regret.

The motor trade is last place anybody with brains should choose and it shows. It's labour intensive and poorly recompensed. I have trained or attempted to train many apprentices over the past 40 years or so. I think it's fair to say that a great many of the aspiring mechanics were basically half-witted.

The training is very poor in all areas compared to the standard in the technical college I attended when I left school in 1971. It's not possible to single out electrical/electronic training. 'Dumbed down' is the phrase that springs to mind.

Training is largely unfit for purpose, but so are most of the trainees.

P.J. O'Rourke was right on the money with this:

"The problem with public school is not overcrowding in the classroom. The problem is not teacher unions. The problem is not underfunding or lack of computer equipment. The problem is your damn kids."
