Is there a way to remove/hide old kernel versions?

On my laptop I have limited space but install all new updates, including kernel updates. However, Ubuntu doesn't seem to uninstall old kernels after installing a new kernel update. I guess this happens with reason: since the new kernel might fail, and it would be nice if GRUB provided a way to select the old kernel to boot with. But do I really need the whole history?, I guess not!:

I thought apt-get autoremove should remove at least some of those images, but it doesn't. I will remove those now by hand, but isn't there a way to do this automatically and to keep, let's say, the last three images? Yes a shell script and a cron job! Any alternatives?
