Jeri Ellsworth did a video about a wasteful 4000 dollar (US) system to warn people about a bus. She pontificates about the utility of such a system, and then does a quick and dirty prototype for far less money.
Someone using the YouTube account PeterBartek, perhaps, possibly the person listed here:

Now, how does a company employ someone so stupid as their "Director of Technology?"
Looks like he doesn't like someone educating taxpayers that he's selling the electronic equivalent of "snake oil" for an inflated price.
I've been a bus electrical system designer, and I've seen a lot of BS companies try to sell their BS products to customers who insist it be on their bus. My guess is free dinners on the taxpayers (eventual) dime sell a lot of useless crap.
