Not true universally. In-car breathalyzers are calibrated regularly; have margins much closer to 10%. They are portable and simple to use.
Maybe in the 'bad old days' it was worse. But today its been scrutinized in court so many times, it has to be bulletproof to get deployed.
Now, blood testing may differ from breath testing. Which is aligned with impaired driving? Breath testing may be the better measure. If state laws are often couched in terms of breath alcohol, then they are the only correct measure.
