It is true that all the evidence as to time and distances was an "estimate" based on best judgment and in dealing in half seconds, two and a half seconds or even three seconds reasonable minds may differ and a calculation of four or five tenths of a second may be "too inexact and approximate to be convincing with the time factor so infinitesimal," State ex rel. Alton R. Co. v. Shain, 346 Mo. 681, 691, 143 S.W.2d 233, 238. But in this case the only evidence we have as to time is the appellant's evidence and, however it was determined, it is a maximum of two and a half seconds. Here there were no conflicts in the estimates in question. It is true that the time was determined by an "expert" but in using the established time we do not hold that the appellant, as a matter of law or duty, was bound to act with the precision and care of an expert. Neither do we hold that by reason of experiments conducted by an expert, not then in peril or acting under an emergency, that the appellant is conclusively bound by the experiment in every detail. Again we repeat, the only evidence we have in all the case, by which the appellant's conduct is to be judged, under the Kansas last chance doctrine, is her own evidence and though it comes from an "expert" it is all there is and it is "two to two and a half seconds" and her case must be adjudged accordingly. *Page 706
The point is that the appellant's own evidence, the only evidence there is on the subject, shows that when the train was three to three and a half seconds away she needed but two or two and a half seconds for safety and if that is all the time needed by her own evidence she had it and yet she failed to utilize it or avail herself of it. Thus, under her own evidence she demonstrates, at best, equal power and chance with the railroad to avoid the catastrophe and under such a showing reasonable minds may not differ and find liability under the last chance doctrine of Kansas. Here the appellant's evidence shows that she could have avoided the collision or, at best, that both she and the railroad could have done so and that demonstrates concurrent as well as contributory negligence and bars recovery under the law of Kansas.
