Yup! Source I have from 2016 has it even more unbalanced than your numbers. All shipping is 1.7% vs all road transport at 11.9%. Wish I had more recent data but their claim wouldn’t be true even if those top ten ships represented the entirety of ocean emissions and was tripled afterwards.

The High Speed Rail project is still underway. It’s been hit by endless cost increases and delays, but it’s still happening — Musk didn’t succeed there. Initial operation for the first segment (Bakersfield to Merced) is, rather depressingly, planned for the early 2030s.

The delays and cost overruns are ridiculous but also absolutely standard for the US. This country is atrocious at building anything more advanced than a single building.
