Your comparison between vehicular homicide and commercial copyright infringement would work better if the perpetrator of the former were not protected by diplomatic immunity.
(1) "In court papers, the former Foreign Office (FCO) minister Tony Baldry said the diplomatic immunity deal reached in 1995 was intended specifically to exclude dangerous driving cases, or indeed any actions not related to the work of the staff at the base"[1]
(2) Even if (1) were not the case, there have been documented cases where the US has "put pressure" on genuine diplomats working on US soil who have committed offences in order to be able to prosecute in the US (something about a Georgian diplomat in 1997 IIRC). Why should the rest of the world be subjected to "do as I say, but not as I do" with the US ?
(3) What about that stupid "surprise surprise" show Trump attempted to put on at the Whitehouse ? I mean that's just sticking two-fingers up in the air to the UK family by saying "well, you can meet the perpetrator who's waiting in the next room ... ready to shed some crocodile tears for the cameras".
Diplomatic immunity is intended to prevent the host country (the UK) from subjecting diplomats to unreasonable detention, imprisonment etc, or to protect them from work done as part of their job (the host country might consider it spying).
Responsible countries either waive the diplomatic immunity, or prosecute the offender in their own courts. The USA has done neither.
In 2002, a Colombian diplomat had his immunity waived, allowing the UK to prosecute him for manslaughter. [1]
Aah yes, about that "diplomatic immunity" ...
