simple. less than 1 sec is enough for a tragedy while driving. this H5-Note would improve my daily life because I drive a lot daily and it would help keep my attention to the road even if someone is calling. just looking on the board instead of trying to search the pockets for an extra hand and ear would be a big plus. who knows maybe an emergency call is trying to get to you.
better be late (or calling later) than sorry that's my opinion when driving without a H5. it's not only me I have to take care but also other passengers and people outside.
but with this magnificent prize I could rest assure that the matter of answering a call while driving is not bad, so yes my life while driving would be a bit more easier with this little fellow.
