Less than you might think. Have you seen Three Felonies a Day[1] ? Or heard of "indict a ham sandwich"[2]?
The law being what it is today, and prosecutorial discretion being what it is, it is almost entirely up to whether someone wants to prosecute.

This is very different from purposefully hiding your emissions levels from testers.
Whether that difference is material when meting out punishment is up to judgement. But calling it "no different" seems pretty wrong.
EDIT: Not exactly that... from another user "They admit that the modified bikes bypass emissions requirements, whereas the unmodified VWs didn't meet the requirements and had to cheat to pass inspection."
What, VW bribed the comission? FBI should arrest them too..
Somebody created emission requirements for motorcycles?
I dropped 20 lbs off a 330lb bike (and added about 5hp) by replacing the heavy dual exhaust with a single Ti/carbon pipe, and reprogramming the ECU. I'm sure the manufacturer would have loved to give me a 310lb bike that made more power if they could. (and before you ask, no it's not loud, I hate loud pipes)
Incidentally, the exhaust/ECU upgrade was done by the local shop when the bike was purchased new. Basically the same as what H-D was doing.
Anyway, what H-D got popped for is arguably less egregious than what VW was doing. They admit that the modified bikes bypass emissions requirements, whereas the unmodified VWs didn't meet the requirements and had to cheat to pass inspection.
Harley also got into the business of selling folks new exhaust/air intake and race tuners at the dealership so folks could 'stage 1' their bikes and remap their EFI units. This results in failing emissions (usually). They settled, restricted what they sell post-sale and are tightening down on what voids factory warranties moving forward.

Your premise is a partial myth anyway.
"35 bankers were sent to prison for financial crisis crimes"
"There have been 59 bankers convicted of crimes"

Don't ever talk to federal investigators. That's your lawyer's job.
Request a lawyer. That's it. Say nothing else.
Textbook case of corruption. Probably one of the biggest and most obvious I've ever seen, too.
There's stupidity and incompetence, and then there's deliberately breaking the law and trying to hide that you're doing so. The latter gets you arrested, the former gets you shamed (and perhaps fined).
The bad switch was the responsibility of one engineer who simply didn't think it was a problem. Once it turned out it was, the switch was redesigned without changing the part number, which is really weird, but doesn't seem to have been part of any sort of coverup. It then took years for realization of the problem to percolate up far enough for the company as a whole to take action.
Maybe. The Justice Department case against GM that was settled had two parts... a wire-fraud charge and a charge of "engaging in a scheme to conceal a deadly safety defect".
Of course, GM settled for $900 million (USD) with an agreement to drop the charges if GM fixes their recall process. So, we don't have a criminal conviction.
I do wonder if GM got off easy because they are American. Next to impossible to prove, lacking a smoking gun (email or similar), but GM actually killed people and got a small fine (relative to VW's fines).
