  In this paper, we re-examine the notion of string stability as it relates to
safety by providing an upper bound on the maximum spacing error of any vehicle
in a homogeneous platoon in terms of the input of the leading vehicle. We
reinforce our previous work on lossy CACC platoons by accommodating for
burst-noise behavior in the V2V link. Further, through Monte Carlo type
simulations, we demonstrate that connectivity can enhance traffic mobility and
safety in a CACC string even when the deceleration capabilities of the vehicles
in the platoon are heterogeneous.
