Hover Street View for RideWithGPS — preview cycling routes

Hover anywhere on a RideWithGPS route and see a Google Street View preview of that exact spot — oriented in the direction the route is heading. Sweep your cursor along the route to scout the entire ride in seconds. The map alone doesn't show road conditions: surface type, shoulder width, traffic. RideWithGPS has Google's pegman built in, but you have to drag it, drop it, peek, back out, and re-drag for every point you want to check. This extension adds a continuous street view hover over the route & elevation map. Features: - Hover near any part of a route to see a Google Street View image - Shows street name and city, plus a compass and heading - Click the preview to open full Google Maps Street View - Works in both the route editor and route viewer, on any public or private route Two modes: * Experimental Preview — no API key needed. Bike trail coverage is limited. The fastest way to try the extension. * Bring your own API key — better bike trail coverage. 10,000 free requests / month from Google's Street View Static API. Requirements: * Google Maps must be selected as the map type in RideWithGPS * (Optional) Google Maps API key with Street View Static API enabled, for the API key mode When using the API key mode, the extension keeps usage under the 10k/month free tier by bucketing nearby points for a better cache hit ratio, skipping redundant requests, and throttling requests as the cursor moves. The popup shows current monthly usage and lets you set a hard monthly cap.
