Especially that about the car... As for flicker, correct about incandescent bulbs but most CFLs nowadays are run on integrated electronic ballasts which increase the on-off cycles to somewhere around 30,000 Hz (= 60,000 pps), in order to reduce flicker. Some sensitive individuals still have adverse reactions to CFLs but if that's probably due to other irritating properties, such as glare, unnatural light colour, discontinuous spectral distribtion, small amounts of UV or RF-emissions from some, etc. (See my site for more info on problems with CFLs.)
