Show HN: EV vs. ICE Breakeven Tool

This started as a quick script to sanity check EV running costs, and turned into a handy little comparison tool.

I haven't been able to find anything which shows at which price points EV is cheaper/more expensive than ICE – the heatmap shows it pretty concisely.

It’s a bit rough round the edges, but people have found it pretty useful, so I figured I'd spin it out into its own site. Sharing for feedback.
