I don't have the full article content to summarize. You've provided the article title "How do you issue a ticket to a robotaxi?" and a brief header from TechCrunch Mobility, but the actual article text is missing.

To write an accurate summary following your strict guidelines, I need:

- The complete article body with details about any startups, funding, founders, or companies mentioned - Specific numbers, funding amounts, and investor names - Company valuations if included - The core narrative and market opportunity

Please share the full article text, and I'll deliver a sharp 150-250 word summary with the CATEGORY and TAGS lines.
