**APIs profiled:** 0

Sidecar (side.cr) was added to the API Evangelist network as a Union Square Ventures portfolio lead. The side.cr domain today hosts a transportation news and information content platform (self-described as "building the largest transportation news source powered by everyday people"), covering ridesharing, driving, delivery, safety, and automotive topics for riders and drivers. It is a reader-facing editorial site, not a developer platform: as of this enrichment pass it publishes no API, developer portal, documentation, SDKs, OpenAPI, or any /.well-known discovery surface. The name echoes the pioneering peer-to-peer Sidecar ridesharing company that Union Square Ventures backed and that wound down in 2015, but the current content site states no operational or corporate ties to that defunct service. This profile is retained as a company/lead record with no active API surface to enrich.
