I agree that would be cool, although with 2018+ cars this is going to get very difficult. Manufacturers are starting to encrypt bus traffic and add firewalls that will prevent unauthorized communication between certain ECUs and from the J1962 connector (aka "OBDII Port").

I work for an auto supplier that supplies vehicle communication software, so I can confirm first hand that some 2018 vehicles currently on sale already have these firewalls:

Which is to keep the evil hackers out, but has the additional benefit that they can have a captive market for a $100 part that would normally be $1. The aftermarket suppliers are locked out of the market because they don't have the private keys to handshake on the bus.

(happily keeping my late 90's car running, although my most recent car literally has gone 100k miles with _NOTHING_ but oil, tires and brake pads). Its now at its first service interval and I'm wondering if I should just trade it in before anything breaks.

I'd keep it until the wheels fell off. I had a 91 Nissan that had very few problems unlike my 13' vw tdi. I'm not excited about the future of automobiles for people that like driving and repairing their own vehicles. With countries legislating gas burning vehicles it's likely to increase the production of electric vehicles and most likely self driving vehicles. Which is great if you want to live a couple hours away and sleep on the way in to work. But imagine the vehicle malfunctioning for something like a simple cold start issue that can be resolved with a can of starter fluid. A quick trip to the part store turns into a month in the service center. Not excited at all.

That is a potential problem, especially for "hacker" type suppliers (offering performance components for example). That said, the manufacturer I work with sells their diagnostic tool to the aftermarket, so at least aftermarket garages can get access for repairs.

Something which is already being seen in the farming market: https://motherboard.vice.com/en_us/article/xykkkd/why-americ...

Yes, the John Deere situation will likely drive change in the automotive world too. There is already a pretty strong "right to repair" law in MA, and it will likely inform the laws that are written in other states or maybe even at a federal level. All automakers have to conform to the MA law already, but I'm not sure if that law applies to farming/John Deere as well.

I'm working at a major auto manufacturer so I can confirm that devices like this are introduced.
