Nice work. I worked on a similar project where I created an adaptive cruise control prototype. I used a camera and a CNN to determine the distance from the car ahead of my car. From there you can adjust your cruise control speed and hopefully maintain a set distance away.

There are clearly some ethical/safety issues with testing the entire thing at once while driving on the road. Some better applications would be an alert for following too close or drifting out of lane. Anyways, I find self driving cars exceptionally interesting and I liked reading your write up.

Great project! It's really interesting that you relied solely on a regular camera for depth perception. Way less expensive than working with RGBD images.

Awesome project, but why Python 2? :( Pre-compiled Python wheels are available for Python 3 on Raspberry Pi at piwheels.org (default for pip in Raspbian)

I'm tired of seeing this comment over and over on HN. Does everyone who writes a Python 2-based project on HN have to explain themselves and provide a valid excuse? Why can't people just be deciding they like Python 2 more than 3, or finding that it's more suitable for their project?

One problem I have with 'adaptive cruise control' in car is that it has no situational awareness. It constantly speeds up and slows down in heavy traffic highway situations, its quite jarring. What i want instead is integration with traffic situation and adapt the speed to that automatically os it doesn't zoom upto 75 mph and come to a stop.

It doesn't seem unreasonable to me to ask why someone would use a version language that is going to be deprecated in just over a year, when newer versions are readily available.

Cool stuff! Do you have plans to expand this further? Would you accept pull requests? :)

I did this project together with my colleague Paula (pksm here, @pksmoraes on Twitter). I am doing research on NLP, this was just one summer project for me. She will work on that project further. So yes, it is not dead! Submit a pull request if you like :)

Yeah like he said I'll be working on employing transfer learning for self-driving cars. :)

Is it that hard to assume they either like it more or they couldn't use a later version because of a dependency? The only scenario this question would be useful in is if they had no idea the later version exists, which is a boat I have yet to see anyone fall into. Unless, I guess, it's one of those "questions" that isn't looking for an answer, but simply looking for an opportunity to chastise...
