  Strong field ionization provides a unique mean to address complex dynamics of
an electron in competing Coulomb and laser fields. Recent streak camera
experiment (K\"ubel, et al., Phys. Rev. Lett. 119, 183201) analyzed asymmetries
in the low-energy region of ejected electron momenta distribution and
associated them with multiple rescattering of the electron on the parent ion.
In this work we directly confirm the multiple rescattering nature of the
asymmetry in the low-energy region. Such electron-ion collisions cannot be
described within one-dimensional simulations even taking into account
focal-volume averaging. Using time-dependent Schr\"odinger equation simulation
in two dimensions supplemented by the insight from strong field semi-classical
approximation we identify the dominant interference features of the complex
photoelectron momentum maps and find their traces in the experiment. In
particular, the holographic structures remain visible in experimental results
averaged over carrier-envelope phase (CEP). In the case of individual momentum
maps when CEP or delay between the two pulses is varied, the structures arising
due to rescattering events are influenced by interfering electrons ionized at
main peaks of the electric field. With an increase of experimental resolution,
such structures record the electron dynamics on a sublaser-cycle time scale.
